 # dwl - dwm for Wayland
 
-Join us on our [Discord server] or at [#dwl] on irc.libera.chat.
+Join us on our IRC channel: [#dwl on Libera Chat]  
+Or on the community-maintained [Discord server].
 
 dwl is a compact, hackable compositor for [Wayland] based on [wlroots]. It is
 intended to fill the same space in the Wayland world that dwm does in X11,
-primarily in terms of philosophy, and secondarily in terms of functionality.
-Like dwm, dwl is:
+primarily in terms of functionality, and secondarily in terms of
+philosophy. Like dwm, dwl is:
 
 - Easy to understand, hack on, and extend with patches
 - One C source file (or a very small number) configurable via `config.h`
-- Limited to 2200 SLOC to promote hackability
 - Tied to as few external dependencies as possible
 
-dwl is not meant to provide every feature under the sun. Instead, like dwm, it
-sticks to features which are necessary, simple, and straightforward to implement
-given the base on which it is built. Implemented default features are:
+## Getting Started:
 
-- Any features provided by dwm/Xlib: simple window borders, tags, keybindings,
-  client rules, mouse move/resize. Providing a built-in status bar is an
-  exception to this goal, to avoid dependencies on font rendering and/or
-  drawing libraries when an external bar could work well.
-- Configurable multi-monitor layout support, including position and rotation
-- Configurable HiDPI/multi-DPI support
-- Idle-inhibit protocol which lets applications such as mpv disable idle
-  monitoring
-- Provide information to external status bars via stdout/stdin
-- Urgency hints via xdg-activate protocol
-- Support screen lockers via input-inhibitor protocol
-- Various Wayland protocols
-- XWayland support as provided by wlroots (can be enabled in `config.mk`)
-- Zero flickering - Wayland users naturally expect that "every frame is perfect"
-- Layer shell popups (used by Waybar)
-- Damage tracking provided by scenegraph API
+### Latest semi-stable [release]
+This is probably where you want to start. This builds against the [wlroots]
+versions currently shipping in major distributions. If your
+distribution's `wlroots` version is older, use an earlier dwl [release].
+The `wlroots` version against which a given `dwl` release builds is specified
+with each release on the [release] page
 
-Features under consideration (possibly as patches) are:
+### Development branch [main]
+Active development progresses on the `main` branch. The `main` branch is built
+against a late (and often changing) git commit of wlroots. While the adventurous
+are welcome to use `main`, it is a rocky road. Using `main` requires that the
+user be willing to chase git commits of wlroots. Testing development pull
+requests may involve merging unmerged pull requests in [wlroots]' git repository
+and/or git commits of wayland.
   
-- Protocols made trivial by wlroots
-- Implement the text-input and input-method protocols to support IME once ibus
-  implements input-method v2 (see https://github.com/ibus/ibus/pull/2256 and
-  https://github.com/djpohly/dwl/pull/235)
+### Building dwl
+dwl has the following dependencies:
+- libinput
+- wayland
+- wlroots (compiled with the libinput backend)
+- xkbcommon
+- wayland-protocols (compile-time only)
+- pkg-config (compile-time only)
 
-Feature *non-goals* for the main codebase include:
+dwl has the following additional dependencies if XWayland support is enabled:
+- libxcb
+- libxcb-wm
+- wlroots (compiled with X11 support)
+- Xwayland (runtime only)
 
-- Client-side decoration (any more than is necessary to tell the clients not to)
-- Client-initiated window management, such as move, resize, and close, which can
-  be done through the compositor
-- Animations and visual effects
+Install these (and their `-devel` versions if your distro has separate
+development packages) and run `make`. If you wish to build against a released
+version of wlroots (*you probably do*), use a [release] or a [0.x branch]. If
+you want to use the unstable development `main` branch, you need to use the git
+version of [wlroots].
 
-## Building dwl
-
-dwl has only two dependencies: `wlroots` and `wayland-protocols`. 
-
-Simply install these (and their `-devel` versions if your distro has separate
-development packages) and run `make`.  If you wish to build against a Git
-version of wlroots, check out the [wlroots-next branch].
-
-To enable XWayland, you should also install xorg-xwayland and uncomment its flag

 ## Running dwl
 
 dwl can be run on any of the backends supported by wlroots. This means you can
-run it as a separate window inside either an X11 or Wayland session, as well
-as directly from a VT console. Depending on your distro's setup, you may need

-enable/start the seatd daemon.

+## Background
+
+dwl is not meant to provide every feature under the sun. Instead, like dwm, it
+sticks to features which are necessary, simple, and straightforward to implement
+given the base on which it is built. Implemented default features are:
+
+- Any features provided by dwm/Xlib: simple window borders, tags, keybindings,
+  client rules, mouse move/resize. Providing a built-in status bar is an
+  exception to this goal, to avoid dependencies on font rendering and/or drawing
+  libraries when an external bar could work well.
+- Configurable multi-monitor layout support, including position and rotation
+- Configurable HiDPI/multi-DPI support
+- Idle-inhibit protocol which lets applications such as mpv disable idle
+  monitoring
+- Provide information to external status bars via stdout/stdin
+- Urgency hints via xdg-activate protocol
+- Support screen lockers via ext-session-lock-v1 protocol
+- Various Wayland protocols
+- XWayland support as provided by wlroots (can be enabled in `config.mk`)
+- Zero flickering - Wayland users naturally expect that "every frame is perfect"
+- Layer shell popups (used by Waybar)
+- Damage tracking provided by scenegraph API
+
+Given the Wayland architecture, dwl has to implement features from dwm **and**
+the xorg-server. Because of this, it is impossible to maintain the original
+project goal of 2000 SLOC and have a reasonably complete compositor with
+features comparable to dwm. However, this does not mean that the code will grow
+indiscriminately. We will try to keep the code as small as possible.
+
+Features under consideration (possibly as patches) are:
+
+- Protocols made trivial by wlroots
+- Implement the text-input and input-method protocols to support IME once ibus
+  implements input-method v2 (see https://github.com/ibus/ibus/pull/2256 and
+  https://codeberg.org/dwl/dwl/pulls/235)
+
+Feature *non-goals* for the main codebase include:
+
+- Client-side decoration (any more than is necessary to tell the clients not to)
+- Client-initiated window management, such as move, resize, and close, which can
+  be done through the compositor
+- Animations and visual effects
+

+  <description summary="Control power management modes of outputs">
+    This protocol allows clients to control power management modes
+    of outputs that are currently part of the compositor space. The
+    intent is to allow special clients like desktop shells to power
+    down outputs when the system is idle.
+
+    To modify outputs not currently part of the compositor space see
+    wlr-output-management.
+
+    Warning! The protocol described in this file is experimental and
+    backward incompatible changes may be made. Backward compatible changes
+    may be added together with the corresponding interface version bump.
+    Backward incompatible changes are done by bumping the version number in
+    the protocol and interface names and resetting the interface version.
+    Once the protocol is to be declared stable, the 'z' prefix and the
+    version number in the protocol and interface names are removed and the
+    interface version number is reset.
