 . On start Waybar throws an exception "error while loading shared libraries: libcava.so: cannot open shared object file: No such file or directory".
   It might happen when libcava for some reason hasn't been registered in the system. sudo ldconfig should help
 . Waybar is starting but cava module doesn't react to the music
-	1. In such cases at first need to make sure usual cava application is working as well
-	2. If so, need to comment all configuration options. Uncomment cava_config and provide the path to the working cava config
-	3. You might set too huge or too small input_delay. Try to setup to 4 seconds, restart waybar, and check again 4 seconds past. Usual even on weak machines it should be enough
-	4. You might accidentally switch action mode to pause mode

+## GLSL
+The Cava GLSL frontend delegates the visualization of incoming audio data to the GPU via OpenGL.
+
+There are some mandatory dependencies that need to be satisfied in order for Cava GLSL to be built and function properly:
+
+. epoxy library must be installed on the system
+. Vertex and fragment shaders from the original project must be used. They should be downloaded, and the file paths must be configured correctly in the Waybar Cava configuration:
+   1. cava shaders [cava shaders](https://github.com/karlstav/cava/tree/master/output/shaders)
+   2. libcava shaders [libcava shaders](https://github.com/LukashonakV/cava/tree/master/output/shaders)
+. It is highly recommended to have a separate cava configuration for the Waybar Cava GLSL module and to use this as the cava_config in the Waybar configuration.
+. It is common for cava configurations to be placed in the XDG_CONFIG_HOME directory, including shaders as well. Consider keeping them in the $XDG_CONFIG_HOME/cava/shaders folder.
+
+Key configuration options:
+
+. bars. The more values the parameter has, the more interesting the visualization becomes.
+. method in output section must be set to sdl_glsl
+. sdl_width and sdl_height manage the size of the module. Adjust them according to your needs.
+. Shaders for sdl_glsl, located in $HOME/.config/cava/shaders. Example: "vertex_shader" = "pass_through.vert" "fragment_shader" = "spectrogram.frag"
+. Set continuous_rendering to 1 to enable smooth rendering; set it to 0 otherwise. It is recommended to keep it set to 1.
+. background, foreground, and gradient_color_N (where N is a number between 1 and 8) must be defined using hex code
+
+Example:
+
+waybar config
+```
+"cava": {
+        "cava_config": "$XDG_CONFIG_HOME/cava/waybar_cava#3.conf",
+        "input_delay": 2,

+## User signal configuration
+
+Config parameters *on-sigusr1* and *on-sigusr2* change what happens when bars receive
+*SIGUSR1* and *SIGUSR2* signals.
+
+This means that commands `killall -SIGUSR1 waybar` and `killall -SIGUSR2 waybar`
+can perform user-configured action.
+
+It also means that if an external script has the PID of the bar then it can
+perform more complex `show`/`hide`/`reload` logic for each instance of Waybar.
+One can find the PID e.g. by doing `pgrep -a waybar` which could then match
+by config name or other parameters.

-    <description summary="list and control workspaces">
-      Workspaces, also called virtual desktops, are groups of surfaces. A
-      compositor with a concept of workspaces may only show some such groups of
-      surfaces (those of 'active' workspaces) at a time. 'Activating' a
-      workspace is a request for the compositor to display that workspace's
-      surfaces as normal, whereas the compositor may hide or otherwise
-      de-emphasise surfaces that are associated only with 'inactive' workspaces.
-      Workspaces are grouped by which sets of outputs they correspond to, and
-      may contain surfaces only from those outputs. In this way, it is possible
-      for each output to have its own set of workspaces, or for all outputs (or
-      any other arbitrary grouping) to share workspaces. Compositors may
-      optionally conceptually arrange each group of workspaces in an
-      N-dimensional grid.
-
-      The purpose of this protocol is to enable the creation of taskbars and
-      docks by providing them with a list of workspaces and their properties,
-      and allowing them to activate and deactivate workspaces.
-
-      After a client binds the zext_workspace_manager_v1, each workspace will be
-      sent via the workspace event.

-      <description summary="a workspace group has been created">
-        This event is emitted whenever a new workspace group has been created.
-
-        All initial details of the workspace group (workspaces, outputs) will be
-        sent immediately after this event via the corresponding events in
-        zext_workspace_group_handle_v1.

-        The client must send this request after it has finished sending other
-        requests. The compositor must process a series of requests preceding a
-        commit request atomically.
-
-        This allows changes to the workspace properties to be seen as atomic,
-        even if they happen via multiple events, and even if they involve
-        multiple zext_workspace_handle_v1 objects, for example, deactivating one

-        properties to be seen as atomic, even if they happen via multiple

-        another sends an output_enter event and an output_leave event to the two
-        zext_workspace_group_handle_v1 objects in question. The compositor sends
