+[#1530]: https://github.com/ratatui/ratatui/pull/1530
+
+To call `Frame::render_widget_ref()` or `Frame::render_stateful_widget_ref()` you now need to:
+
+1. Import the `FrameExt` trait from `ratatui::widgets`.
+2. Enable the `unstable-widget-ref` feature.
+
+For example:
+
+```rust
+use ratatui::{
+    layout::Rect,
+    widgets::{Block, FrameExt},
+};
+
+let block = Block::new();
+let area = Rect::new(0, 0, 5, 5);
+frame.render_widget_ref(&block, area);
+```
+
+### `WidgetRef` no longer has a blanket implementation of Widget
+
+Previously there was a blanket implementation of Widget for WidgetRef. This has been reversed to
+instead be a blanket implementation of WidgetRef for all &W where W: Widget. Any widgets that
+previously implemented WidgetRef directly should now instead implement Widget for a reference to the
+type.
+
+```diff
+-impl WidgetRef for Foo {
+-    fn render_ref(&self, area: Rect, buf: &mut Buffer)
++impl Widget for &Foo {
++    fn render(self, area: Rect, buf: &mut Buffer)
+}
+```
+
+### The `From` impls for backend types are now replaced with more specific traits [#1464]
+
+[#1464]: https://github.com/ratatui/ratatui/pull/1464
+
+Crossterm gains `ratatui::backend::crossterm::{FromCrossterm, IntoCrossterm}`
+Termwiz gains `ratatui::backend::termwiz::{FromTermwiz, IntoTermwiz}`
+
+This is necessary in order to avoid the orphan rule when implementing `From` for crossterm types
+once the crossterm types are moved to a separate crate.
+
+```diff
++ use ratatui::backend::crossterm::{FromCrossterm, IntoCrossterm};
+
+let crossterm_color = crossterm::style::Color::Black;
+- let ratatui_color = crossterm_color.into();
+- let ratatui_color = ratatui::style::Color::from(crossterm_color);
++ let ratatui_color = ratatui::style::Color::from_crossterm(crossterm_color);
+- let crossterm_color = ratatui_color.into();
+- let crossterm_color = crossterm::style::Color::from(ratatui_color);
++ let crossterm_color = ratatui_color.into_crossterm();
+
+let crossterm_attribute = crossterm::style::types::Attribute::Bold;
+- let ratatui_modifier = crossterm_attribute.into();
+- let ratatui_modifier = ratatui::style::Modifier::from(crossterm_attribute);
++ let ratatui_modifier = ratatui::style::Modifier::from_crossterm(crossterm_attribute);
+- let crossterm_attribute = ratatui_modifier.into();
+- let crossterm_attribute = crossterm::style::types::Attribute::from(ratatui_modifier);
++ let crossterm_attribute = ratatui_modifier.into_crossterm();
+```
+
+Similar conversions for `ContentStyle` -> `Style` and `Attributes` -> `Modifier` exist for
+Crossterm and the various Termion and Termwiz types as well.
+
+### `Bar::label()` and `BarGroup::label()` now accepts `Into<Line<'a>>`. ([#1471])
+
+[#1471]: https://github.com/ratatui/ratatui/pull/1471
+
+Previously `Bar::label()` and `BarGroup::label()` accepted `Line<'a>`, but they now accepts `Into<Line<'a>>`.
+
+for `Bar::label()`:
+
+```diff
+- Bar::default().label("foo".into());
++ Bar::default().label("foo");

+
+### `Bar::text_value` now accepts `Into<String>` ([#1471])
+
+Previously `Bar::text_value` accepted `String`, but now it accepts `Into<String>`.
+

+
+```diff

+```
+
+## [v0.29.0](https://github.com/ratatui/ratatui/releases/tag/v0.29.0)
+
+### `Sparkline::data` takes `IntoIterator<Item = SparklineBar>` instead of `&[u64]` and is no longer const ([#1326])
+
+[#1326]: https://github.com/ratatui/ratatui/pull/1326
+
+The `Sparkline::data` method has been modified to accept `IntoIterator<Item = SparklineBar>`
+instead of `&[u64]`.
+
+`SparklineBar` is a struct that contains an `Option<u64>` value, which represents an possible
+_absent_ value, as distinct from a `0` value. This change allows the `Sparkline` to style
+data points differently, depending on whether they are present or absent.
+
+`SparklineBar` also contains an `Option<Style>` that will be used to apply a style the bar in
+addition to any other styling applied to the `Sparkline`.
+
+Several `From` implementations have been added to `SparklineBar` to support existing callers who
+provide `&[u64]` and other types that can be converted to `SparklineBar`, such as `Option<u64>`.
+
+If you encounter any type inference issues, you may need to provide an explicit type for the data
+passed to `Sparkline::data`. For example, if you are passing a single value, you may need to use
+`into()` to convert it to form that can be used as a `SparklineBar`:
+
+```diff
+let value = 1u8;
+- Sparkline::default().data(&[value.into()]);
++ Sparkline::default().data(&[u64::from(value)]);
+```
+
+As a consequence of this change, the `data` method is no longer a `const fn`.
+
+### `Color::from_hsl` is now behind the `palette` feature and accepts `palette::Hsl` ([#1418])
+
+[#1418]: https://github.com/ratatui/ratatui/pull/1418
+
+Previously `Color::from_hsl` accepted components as individual f64 parameters. It now accepts a
+single `palette::Hsl` value and is gated behind a `palette` feature flag.
+
+```diff
+- Color::from_hsl(360.0, 100.0, 100.0)
++ Color::from_hsl(Hsl::new(360.0, 100.0, 100.0))
+```
+
+### Removed public fields from `Rect` iterators ([#1358], [#1424])
+
+[#1358]: https://github.com/ratatui/ratatui/pull/1358
+[#1424]: https://github.com/ratatui/ratatui/pull/1424
+
+The `pub` modifier has been removed from fields on the `Columns`,`Rows`, and `Positions` iterators.
+These fields were not intended to be public and should not have been accessed directly.
+
+### `Rect::area()` now returns u32 instead of u16 ([#1378])
+
+[#1378]: https://github.com/ratatui/ratatui/pull/1378
+
+This is likely to impact anything which relies on `Rect::area` maxing out at u16::MAX. It can now
+return up to u16::MAX * u16::MAX (2^32 - 2^17 + 1).
+
+### `Line` now implements `From<Cow<str>` ([#1373])
+
+[#1373]: https://github.com/ratatui/ratatui/pull/1373
+
+As this adds an extra conversion, ambiguous inferred expressions may no longer compile.
+
+```rust
+// given:
+struct Foo { ... }
+impl From<Foo> for String { ... }
+impl From<Foo> for Cow<str> { ... }
+
+let foo = Foo { ... };
+let line = Line::from(foo); // now fails due to now ambiguous inferred type
+// replace with e.g.
+let line = Line::from(String::from(foo));
+```
+
+### `Tabs::select()` now accepts `Into<Option<usize>>` ([#1413])
+
+[#1413]: https://github.com/ratatui/ratatui/pull/1413
+
+Previously `Tabs::select()` accepted `usize`, but it now accepts `Into<Option<usize>>`. This breaks
+any code already using parameter type inference:
+
+```diff
+let selected = 1u8;
+- let tabs = Tabs::new(["A", "B"]).select(selected.into())
++ let tabs = Tabs::new(["A", "B"]).select(selected as usize)
+```
+
+### `Table::highlight_style` is now `Table::row_highlight_style` ([#1331])
+
+[#1331]: https://github.com/ratatui/ratatui/pull/1331
+
+The `Table::highlight_style` is now deprecated in favor of `Table::row_highlight_style`.
+
+Also, the serialized output of the `TableState` will now include the "selected_column" field.
+Software that manually parse the serialized the output (with anything other than the `Serialize`
+implementation on `TableState`) may have to be refactored if the "selected_column" field is not
+accounted for. This does not affect users who rely on the `Deserialize`, or `Serialize`
+implementation on the state.
+
+## [v0.28.0](https://github.com/ratatui/ratatui/releases/tag/v0.28.0)
+
+### `Backend::size` returns `Size` instead of `Rect` ([#1254])
+
+[#1254]: https://github.com/ratatui/ratatui/pull/1254
+
+The `Backend::size` method returns a `Size` instead of a `Rect`.
+There is no need for the position here as it was always 0,0.
+
+### `Backend` trait migrates to `get/set_cursor_position` ([#1284])
+
+[#1284]: https://github.com/ratatui/ratatui/pull/1284
+
+If you just use the types implementing the `Backend` trait, you will see deprecation hints but
+nothing is a breaking change for you.
+
+If you implement the Backend trait yourself, you need to update the implementation and add the
+`get/set_cursor_position` method. You can remove the `get/set_cursor` methods as they are deprecated
+and a default implementation for them exists.
+
+### Ratatui now requires Crossterm 0.28.0 ([#1278])
+
+[#1278]: https://github.com/ratatui/ratatui/pull/1278
+
+Crossterm is updated to version 0.28.0, which is a semver incompatible version with the previous
+version (0.27.0). Ratatui re-exports the version of crossterm that it is compatible with under
+`ratatui::crossterm`, which can be used to avoid incompatible versions in your dependency list.
+
+### `Axis::labels()` now accepts `IntoIterator<Into<Line>>` ([#1273] and [#1283])
+
+[#1273]: https://github.com/ratatui/ratatui/pull/1173
+[#1283]: https://github.com/ratatui/ratatui/pull/1283
+
+Previously Axis::labels accepted `Vec<Span>`. Any code that uses conversion methods that infer the
+type will need to be rewritten as the compiler cannot infer the correct type.
+
+```diff
+- Axis::default().labels(vec!["a".into(), "b".into()])
++ Axis::default().labels(["a", "b"])
+```
+
+### `Layout::init_cache` no longer returns bool and takes a `NonZeroUsize` instead of `usize` ([#1245])
+
+[#1245]: https://github.com/ratatui/ratatui/pull/1245
+
+```diff
+- let is_initialized = Layout::init_cache(100);
++ Layout::init_cache(NonZeroUsize::new(100).unwrap());
+```
+
+### `ratatui::terminal` module is now private ([#1160])
+
+[#1160]: https://github.com/ratatui/ratatui/pull/1160
+
+The `terminal` module is now private and can not be used directly. The types under this module are
+exported from the root of the crate. This reduces clashes with other modules in the backends that
+are also named terminal, and confusion about module exports for newer Rust users.
+
+```diff
+- use ratatui::terminal::{CompletedFrame, Frame, Terminal, TerminalOptions, ViewPort};
++ use ratatui::{CompletedFrame, Frame, Terminal, TerminalOptions, ViewPort};
+```
+
+### `ToText` no longer has a lifetime ([#1234])
+
+[#1234]: https://github.com/ratatui/ratatui/pull/1234
+
+This change simplifies the trait and makes it easier to implement.
+
+### `Frame::size` is deprecated and renamed to `Frame::area` ([#1293])
+
+[#1293]: https://github.com/ratatui/ratatui/pull/1293
+
+`Frame::size` is renamed to `Frame::area` as it's the more correct name.
+
+## [v0.27.0](https://github.com/ratatui/ratatui/releases/tag/v0.27.0)
+
+### List no clamps the selected index to list ([#1159])
+
+[#1149]: https://github.com/ratatui/ratatui/pull/1149
+
+The `List` widget now clamps the selected index to the bounds of the list when navigating with
+`first`, `last`, `previous`, and `next`, as well as when setting the index directly with `select`.
+
+Previously selecting an index past the end of the list would show treat the list as having a
+selection which was not visible. Now the last item in the list will be selected instead.
+
+### Prelude items added / removed ([#1149])
+
+The following items have been removed from the prelude:
+
+- `style::Styled` - this trait is useful for widgets that want to
+  support the Stylize trait, but it adds complexity as widgets have two
+  `style` methods and a `set_style` method.
+- `symbols::Marker` - this item is used by code that needs to draw to
+  the `Canvas` widget, but it's not a common item that would be used by
+  most users of the library.
+- `terminal::{CompletedFrame, TerminalOptions, Viewport}` - these items
+  are rarely used by code that needs to interact with the terminal, and
+  they're generally only ever used once in any app.
+
+The following items have been added to the prelude:
+
+- `layout::{Position, Size}` - these items are used by code that needs
+  to interact with the layout system. These are newer items that were
+  added in the last few releases, which should be used more liberally.
+  This may cause conflicts for types defined elsewhere with a similar
+  name.
+
+To update your app:
+
+```diff
+// if your app uses Styled::style() or Styled::set_style():
+-use ratatui::prelude::*;
++use ratatui::{prelude::*, style::Styled};
+
+// if your app uses symbols::Marker:
+-use ratatui::prelude::*;
++use ratatui::{prelude::*, symbols::Marker}
+
+// if your app uses terminal::{CompletedFrame, TerminalOptions, Viewport}
+-use ratatui::prelude::*;
++use ratatui::{prelude::*, terminal::{CompletedFrame, TerminalOptions, Viewport}};
+
+// to disambiguate existing types named Position or Size:
+- use some_crate::{Position, Size};
+- let size: Size = ...;
+- let position: Position = ...;
++ let size: some_crate::Size = ...;
++ let position: some_crate::Position = ...;
+```
+
+### Termion is updated to 4.0 [#1106]
+
+Changelog: <https://gitlab.redox-os.org/redox-os/termion/-/blob/master/CHANGELOG.md>
+
+A change is only necessary if you were matching on all variants of the `MouseEvent` enum without a
+wildcard. In this case, you need to either handle the two new variants, `MouseLeft` and
+`MouseRight`, or add a wildcard.

+Previously, `Stylize::bg()` accepted `Color` but now accepts `Into<Color>`. This allows more

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+https://forum.ratatui.rs/ or https://discord.gg/pMCEU9hNEj.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

-#! The crate provides a set of optional features that can be enabled in your `cargo.toml` file.

-# Ratatui
-
-[Ratatui][Ratatui Website] is a crate for cooking up terminal user interfaces in Rust. It is a
-lightweight library that provides a set of widgets and utilities to build complex Rust TUIs.
-Ratatui was forked from the [tui-rs] crate in 2023 in order to continue its development.
-
-## Installation
-
-Add `ratatui` and `crossterm` as dependencies to your cargo.toml:
-
-```shell
-cargo add ratatui crossterm
-```
-
-Ratatui uses [Crossterm] by default as it works on most platforms. See the [Installation]
-section of the [Ratatui Website] for more details on how to use other backends ([Termion] /
-[Termwiz]).
-
-## Introduction
-
-Ratatui is based on the principle of immediate rendering with intermediate buffers. This means
-that for each frame, your app must render all widgets that are supposed to be part of the UI.
-This is in contrast to the retained mode style of rendering where widgets are updated and then
-automatically redrawn on the next frame. See the [Rendering] section of the [Ratatui Website]
-for more info.
-
-You can also watch the [FOSDEM 2024 talk] about Ratatui which gives a brief introduction to
-terminal user interfaces and showcases the features of Ratatui, along with a hello world demo.
-
-## Other documentation
-
-- [Ratatui Website] - explains the library's concepts and provides step-by-step tutorials
-- [API Docs] - the full API documentation for the library on docs.rs.
-- [Examples] - a collection of examples that demonstrate how to use the library.
-- [Contributing] - Please read this if you are interested in contributing to the project.
-- [Changelog] - generated by [git-cliff] utilizing [Conventional Commits].
-- [Breaking Changes] - a list of breaking changes in the library.
+[Ratatui][Ratatui Website] (_ˌræ.təˈtu.i_) is a Rust crate for cooking up terminal user interfaces
+(TUIs). It provides a simple and flexible way to create text-based user interfaces in the terminal,
+which can be used for command-line applications, dashboards, and other interactive console programs.
 
 ## Quickstart
 
-The following example demonstrates the minimal amount of code necessary to setup a terminal and
-render "Hello World!". The full code for this example which contains a little more detail is in
-the [Examples] directory. For more guidance on different ways to structure your application see
-the [Application Patterns] and [Hello World tutorial] sections in the [Ratatui Website] and the
-various [Examples]. There are also several starter templates available in the [templates]
-repository.
+Ratatui has [templates] available to help you get started quickly. You can use the
+[`cargo-generate`] command to create a new project with Ratatui:
 
-Every application built with `ratatui` needs to implement the following steps:
+```shell
+cargo install --locked cargo-generate
+cargo generate ratatui/templates
+```
 
-- Initialize the terminal
-- A main loop to:
-  - Handle input events
-  - Draw the UI
-- Restore the terminal state
-
-The library contains a [`prelude`] module that re-exports the most commonly used traits and
-types for convenience. Most examples in the documentation will use this instead of showing the
-full path of each type.
-
-### Initialize and restore the terminal
-
-The [`Terminal`] type is the main entry point for any Ratatui application. It is a light
-abstraction over a choice of [`Backend`] implementations that provides functionality to draw
-each frame, clear the screen, hide the cursor, etc. It is parametrized over any type that
-implements the [`Backend`] trait which has implementations for [Crossterm], [Termion] and
-[Termwiz].
-
-Most applications should enter the Alternate Screen when starting and leave it when exiting and
-also enable raw mode to disable line buffering and enable reading key events. See the [`backend`
-module] and the [Backends] section of the [Ratatui Website] for more info.
-
-### Drawing the UI
-
-The drawing logic is delegated to a closure that takes a [`Frame`] instance as argument. The
-[`Frame`] provides the size of the area to draw to and allows the app to render any [`Widget`]
-using the provided [`render_widget`] method. See the [Widgets] section of the [Ratatui Website]
-for more info.
-
-### Handling events
-
-Ratatui does not include any input handling. Instead event handling can be implemented by
-calling backend library methods directly. See the [Handling Events] section of the [Ratatui
-Website] for more info. For example, if you are using [Crossterm], you can use the
-[`crossterm::event`] module to handle events.
-
-### Example
+Selecting the Hello World template produces the following application:
 
 ```rust
-use std::io::{self, stdout};
+use color_eyre::Result;
+use crossterm::event::{self, Event};
+use ratatui::{DefaultTerminal, Frame};
 
-use crossterm::{
-    event::{self, Event, KeyCode},
-    terminal::{disable_raw_mode, enable_raw_mode, EnterAlternateScreen, LeaveAlternateScreen},
-    ExecutableCommand,
-};
-use ratatui::{prelude::*, widgets::*};
-
-fn main() -> io::Result<()> {
-    enable_raw_mode()?;
-    stdout().execute(EnterAlternateScreen)?;
-    let mut terminal = Terminal::new(CrosstermBackend::new(stdout()))?;
-
-    let mut should_quit = false;
-    while !should_quit {
-        terminal.draw(ui)?;
-        should_quit = handle_events()?;
-    }
-
-    disable_raw_mode()?;
-    stdout().execute(LeaveAlternateScreen)?;
-    Ok(())
+fn main() -> Result<()> {
+    color_eyre::install()?;
+    let terminal = ratatui::init();
+    let result = run(terminal);
+    ratatui::restore();
+    result
 }
 
-fn handle_events() -> io::Result<bool> {
-    if event::poll(std::time::Duration::from_millis(50))? {
-        if let Event::Key(key) = event::read()? {
-            if key.kind == event::KeyEventKind::Press && key.code == KeyCode::Char('q') {
-                return Ok(true);
-            }
+fn run(mut terminal: DefaultTerminal) -> Result<()> {
+    loop {
+        terminal.draw(render)?;
+        if matches!(event::read()?, Event::Key(_)) {
+            break Ok(());
         }
     }
-    Ok(false)
 }
 
-fn ui(frame: &mut Frame) {
-    frame.render_widget(
-        Paragraph::new("Hello World!")
-            .block(Block::default().title("Greeting").borders(Borders::ALL)),
-        frame.size(),
-    );
+fn render(frame: &mut Frame) {
+    frame.render_widget("hello world", frame.area());
 }
 ```

+## Documentation
 
-## Layout
+- [Ratatui Website] - explains the library's concepts and provides step-by-step tutorials.
+- [Ratatui Forum][Forum] - a place to ask questions and discuss the library.
+- [API Docs] - the full API documentation for the library on docs.rs.
+- [Widget Examples] - a collection of examples that demonstrate how to use the library.
+- [App Examples] - a collection of more complex examples that demonstrate how to build apps.
+- [Changelog] - generated by [git-cliff] utilizing [Conventional Commits].
+- [Breaking Changes] - a list of breaking changes in the library.
 
-The library comes with a basic yet useful layout management object called [`Layout`] which
-allows you to split the available space into multiple areas and then render widgets in each
-area. This lets you describe a responsive terminal UI by nesting layouts. See the [Layout]
-section of the [Ratatui Website] for more info.
+You can also watch the [EuroRust 2024 talk] to learn about common concepts in Ratatui and what's
+possible to build with it.
 
-```rust
-use ratatui::{prelude::*, widgets::*};
+## Templates
 
-fn ui(frame: &mut Frame) {
-    let main_layout = Layout::new(
-        Direction::Vertical,
-        [
-            Constraint::Length(1),
-            Constraint::Min(0),
-            Constraint::Length(1),
-        ],
-    )
-    .split(frame.size());
-    frame.render_widget(
-        Block::new().borders(Borders::TOP).title("Title Bar"),
-        main_layout[0],
-    );
-    frame.render_widget(
-        Block::new().borders(Borders::TOP).title("Status Bar"),
-        main_layout[2],
-    );
+If you're looking to get started quickly, you can use one of the available templates from the
+[templates] repository using [`cargo-generate`]:
 
-    let inner_layout = Layout::new(
-        Direction::Horizontal,
-        [Constraint::Percentage(50), Constraint::Percentage(50)],
-    )
-    .split(main_layout[1]);
-    frame.render_widget(
-        Block::default().borders(Borders::ALL).title("Left"),
-        inner_layout[0],
-    );
-    frame.render_widget(
-        Block::default().borders(Borders::ALL).title("Right"),
-        inner_layout[1],
-    );
-}
+```shell
+cargo generate ratatui/templates
 ```

-## Text and styling
-
-The [`Text`], [`Line`] and [`Span`] types are the building blocks of the library and are used in
-many places. [`Text`] is a list of [`Line`]s and a [`Line`] is a list of [`Span`]s. A [`Span`]
-is a string with a specific style.
-
-The [`style` module] provides types that represent the various styling options. The most
-important one is [`Style`] which represents the foreground and background colors and the text
-attributes of a [`Span`]. The [`style` module] also provides a [`Stylize`] trait that allows
-short-hand syntax to apply a style to widgets and text. See the [Styling Text] section of the
-[Ratatui Website] for more info.
-
-```rust
-use ratatui::{prelude::*, widgets::*};
-
-fn ui(frame: &mut Frame) {
-    let areas = Layout::new(
-        Direction::Vertical,
-        [
-            Constraint::Length(1),
-            Constraint::Length(1),
-            Constraint::Length(1),
-            Constraint::Length(1),
-            Constraint::Min(0),
-        ],
-    )
-    .split(frame.size());
-
-    let span1 = Span::raw("Hello ");
-    let span2 = Span::styled(
-        "World",
-        Style::new()
-            .fg(Color::Green)
-            .bg(Color::White)
-            .add_modifier(Modifier::BOLD),
-    );
-    let span3 = "!".red().on_light_yellow().italic();
-
-    let line = Line::from(vec![span1, span2, span3]);
-    let text: Text = Text::from(vec![line]);
-
-    frame.render_widget(Paragraph::new(text), areas[0]);
-    // or using the short-hand syntax and implicit conversions
-    frame.render_widget(
-        Paragraph::new("Hello World!".red().on_white().bold()),
-        areas[1],
-    );
-
-    // to style the whole widget instead of just the text
-    frame.render_widget(
-        Paragraph::new("Hello World!").style(Style::new().red().on_white()),
-        areas[2],
-    );
-    // or using the short-hand syntax
-    frame.render_widget(Paragraph::new("Hello World!").blue().on_yellow(), areas[3]);

-## Status of this fork
-
-In response to the original maintainer [**Florian Dehau**](https://github.com/fdehau)'s issue
-regarding the [future of `tui-rs`](https://github.com/fdehau/tui-rs/issues/654), several members of
-the community forked the project and created this crate. We look forward to continuing the work
-started by Florian 🚀
-
-In order to organize ourselves, we currently use a [Discord server](https://discord.gg/pMCEU9hNEj),
-feel free to join and come chat! There is also a [Matrix](https://matrix.org/) bridge available at
-[#ratatui:matrix.org](https://matrix.to/#/#ratatui:matrix.org).
-
-While we do utilize Discord for coordinating, it's not essential for contributing.
-Our primary open-source workflow is centered around GitHub.
-For significant discussions, we rely on GitHub — please open an issue, a discussion or a PR.
-
-Please make sure you read the updated [contributing](./CONTRIBUTING.md) guidelines, especially if
-you are interested in working on a PR or issue opened in the previous repository.
-
-## Rust version requirements
-
-Since version 0.23.0, The Minimum Supported Rust Version (MSRV) of `ratatui` is 1.67.0.
-
-## Widgets
-
-### Built in
-
-The library comes with the following
-[widgets](https://docs.rs/ratatui/latest/ratatui/widgets/index.html):
-
-- [BarChart](https://docs.rs/ratatui/latest/ratatui/widgets/struct.BarChart.html)
-- [Block](https://docs.rs/ratatui/latest/ratatui/widgets/block/struct.Block.html)
-- [Calendar](https://docs.rs/ratatui/latest/ratatui/widgets/calendar/index.html)
-- [Canvas](https://docs.rs/ratatui/latest/ratatui/widgets/canvas/struct.Canvas.html) which allows
-  rendering [points, lines, shapes and a world
-  map](https://docs.rs/ratatui/latest/ratatui/widgets/canvas/index.html)
-- [Chart](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Chart.html)
-- [Clear](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Clear.html)
-- [Gauge](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Gauge.html)
-- [List](https://docs.rs/ratatui/latest/ratatui/widgets/struct.List.html)
-- [Paragraph](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Paragraph.html)
-- [Scrollbar](https://docs.rs/ratatui/latest/ratatui/widgets/scrollbar/struct.Scrollbar.html)
-- [Sparkline](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Sparkline.html)
-- [Table](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Table.html)
-- [Tabs](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Tabs.html)

-Each widget has an associated example which can be found in the [Examples] folder. Run each example
-with cargo (e.g. to run the gauge example `cargo run --example gauge`), and quit by pressing `q`.
-
-You can also run all examples by running `cargo make run-examples` (requires `cargo-make` that can
-be installed with `cargo install cargo-make`).

-## How to update these examples
-
-These gifs were created using [VHS](https://github.com/charmbracelet/vhs). Each example has a
-corresponding `.tape` file that holds instructions for how to generate the images. Note that the
-images themselves are stored in a separate `images` git branch to avoid bloating the main
-repository.
-
-<!--
-
-Links to images to make them easier to update in bulk. Use the following script to update and upload
-the examples to the images branch. (Requires push access to the branch).
-
-```shell
-examples/vhs/generate.bash

+//! # [Ratatui] Async example
+//!
+//! This example demonstrates how to use Ratatui with widgets that fetch data asynchronously. It
+//! uses the `octocrab` crate to fetch a list of pull requests from the GitHub API.
+//!
+//! <https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#creating-a-fine-grained-personal-access-token>
+//! <https://github.com/settings/tokens/new> to create a new token (select classic, and no scopes)
+//!
+//! This example does not cover message passing between threads, it only demonstrates how to manage
+//! shared state between the main thread and a background task, which acts mostly as a one-shot
+//! fetcher. For more complex scenarios, you may need to use channels or other synchronization
+//! primitives.
+//!
+//! A simple app might have multiple widgets that fetch data from different sources, and each widget
+//! would have its own background task to fetch the data. The main thread would then render the
+//! widgets with the latest data.
+//!
+//! The latest version of this example is available in the [examples] folder in the repository.
+//!
+//! Please note that the examples are designed to be run against the `main` branch of the Github
+//! repository. This means that you may not be able to compile with the latest release version on
+//! crates.io, or the one that you have installed locally.
+//!
+//! See the [examples readme] for more information on finding examples that match the version of the
+//! library you are using.

+# Input Form example
+
+This example demonstrates how to handle input across several form fields (2 strings and an number).
+It uses an enum to track the focused field, and sends keyboard events to one which is current.
+
+Run this example with:
+
+```shell
+cargo run -p input-form
+```
+
+This example does not handle things like cursor movement within the line (just keys and backspace).
+Most apps would benefit from using the following crates for text input rather than directly using
+strings:
+
+- [`tui-input`](https://crates.io/crates/tui-input)
+- [`tui-prompts`](https://crates.io/crates/tui-prompts)
+- [`tui-textarea`](https://crates.io/crates/tui-textarea)
+- [`rat-salsa`](https://crates.io/crates/rat-salsa)
+
+Some more ideas for handling focus can be found in:
+
+- [`focusable`](https://crates.io/crates/focusable) (see also [Ratatui forum
+  post](https://forum.ratatui.rs/t/focusable-crate-manage-focus-state-for-your-widgets/73))
+- [`rat-focus`](https://crates.io/crates/rat-focus)
+- A useful [`Bevy` discssion](https://github.com/bevyengine/bevy/discussions/15374) about focus

-//! [tui-big-text] is a rust crate that renders large pixel text as a [Ratatui] widget using the
-//! glyphs from the [font8x8] crate.
-//!
-//! ![Hello World example](https://vhs.charm.sh/vhs-2UxNc2SJgiNqHoowbsXAMW.gif)
-//!
-//! # Installation
-//!
-//! ```shell
-//! cargo add ratatui tui-big-text
-//! ```
-//!
-//! # Usage
-//!
-//! Create a [`BigText`] widget using `BigTextBuilder` and pass it to [`Frame::render_widget`] to
-//! render be rendered. The builder allows you to customize the [`Style`] of the widget and the
-//! [`PixelSize`] of the glyphs. The [`PixelSize`] can be used to control how many character cells
-//! are used to represent a single pixel of the 8x8 font.
-//!
-//! # Example
-//!
-//! ```rust
-//! use anyhow::Result;
-//! use ratatui::prelude::*;
-//! use tui_big_text::{BigTextBuilder, PixelSize};
-//!
-//! fn render(frame: &mut Frame) -> Result<()> {
-//!     let big_text = BigTextBuilder::default()
-//!         .pixel_size(PixelSize::Full)
-//!         .style(Style::new().blue())
-//!         .lines(vec![
-//!             "Hello".red().into(),
-//!             "World".white().into(),
-//!             "~~~~~".into(),
-//!         ])
-//!         .build()?;
-//!     frame.render_widget(big_text, frame.size());
-//!     Ok(())

-//! How to use a panic hook to reset the terminal before printing the panic to
-//! the terminal.
-//!
-//! When exiting normally or when handling `Result::Err`, we can reset the
-//! terminal manually at the end of `main` just before we print the error.
-//!
-//! Because a panic interrupts the normal control flow, manually resetting the
-//! terminal at the end of `main` won't do us any good. Instead, we need to
-//! make sure to set up a panic hook that first resets the terminal before
-//! handling the panic. This both reuses the standard panic hook to ensure a
-//! consistent panic handling UX and properly resets the terminal to not
-//! distort the output.
-//!
-//! That's why this example is set up to show both situations, with and without
-//! the chained panic hook, to see the difference.

-
-// A simple example demonstrating how to handle user input. This is a bit out of the scope of
-// the library as it does not provide any input handling out of the box. However, it may helps
-// some to get started.
-//
-// This is a very simple example:
-//   * An input box always focused. Every character you type is registered here.
-//   * An entered character is inserted at the cursor position.
-//   * Pressing Backspace erases the left character before the cursor position
-//   * Pressing Enter pushes the current input in the history of previous messages. **Note: ** as
-//   this is a relatively simple example unicode characters are unsupported and their use will
-// result in undefined behaviour.
-//

+
+**ratatui-core** is the core library of the [ratatui] project,
+providing the essential building blocks for creating rich terminal user interfaces in Rust.
+
+[ratatui]: https://github.com/ratatui/ratatui
+
+### Why `ratatui-core`?
+
+The `ratatui-core` crate is split from the main [`ratatui`](https://crates.io/crates/ratatui) crate
+to offer better stability for widget library authors. Widget libraries should generally depend
+on `ratatui-core`, benefiting from a stable API and reducing the need for frequent updates.
+
+Applications, on the other hand, should depend on the main `ratatui` crate, which includes
+built-in widgets and additional features.
+
+## Installation
+
+Add `ratatui-core` to your `Cargo.toml`:
+
+```shell
+cargo add ratatui-core
+```
+
+## Contributing
