-        implementation-dependent - do not assume that this region will not
-        actually be occluded.
-
-        A positive value is only meaningful if the surface is anchored to one
-        edge or an edge and both perpendicular edges. If the surface is not
-        anchored, anchored to only two perpendicular edges (a corner), anchored
-        to only two parallel edges or anchored to all edges, a positive value
-        will be treated the same as zero.
-
-        A positive zone is the distance from the edge in surface-local
-        coordinates to consider exclusive.
-
-        Surfaces that do not wish to have an exclusive zone may instead specify
-        how they should interact with surfaces that do. If set to zero, the
-        surface indicates that it would like to be moved to avoid occluding
-        surfaces with a positive exclusive zone. If set to -1, the surface
-        indicates that it would not like to be moved to accommodate for other
-        surfaces, and the compositor should extend it all the way to the edges
-        it is anchored to.
-
-        For example, a panel might set its exclusive zone to 10, so that
-        maximized shell surfaces are not shown on top of it. A notification
-        might set its exclusive zone to 0, so that it is moved to avoid
-        occluding the panel, but shell surfaces are shown underneath it. A
-        wallpaper or lock screen might set their exclusive zone to -1, so that
-        they stretch below or over the panel.

+# C FFI module
+
+A C FFI module is a dynamic library that exposes standard C functions and
+constants, that Waybar can load and execute to create custom advanced widgets.
+
+Most language can implement the required functions and constants (C, C++, Rust,
+Go, Python, ...), meaning you can develop custom modules using your language of
+choice, as long as there's GTK bindings.
+
+Symbols to implement are documented in the
+[waybar_cffi_module.h](waybar_cffi_module.h) file.
+
+# Usage
+
+## Building this module
+
+```bash
+meson setup build
+meson compile -C build
+```
+
+## Load the module
+
+Edit your waybar config:
+```json
+{
+	// ...
+	"modules-center": [
+		// ...
+		"cffi/c_example"
+	],
