+  <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.

+# Wayland implementation in Go
+
+[![Go Reference](https://pkg.go.dev/badge/github.com/AvengeMedia/DankMaterialShell/core/pkg/go-wayland/wayland.svg)](https://pkg.go.dev/github.com/AvengeMedia/DankMaterialShell/core/pkg/go-wayland/wayland)
+
+This module contains pure Go implementation of the Wayland protocol.
+Currently only wayland-client functionality is supported.
+
+Go code is generated from protocol XML files using
+[`go-wayland-scanner`](cmd/go-wayland-scanner/scanner.go).
+
+To load cursor, minimal port of `wayland-cursor` & `xcursor` in pure Go
+is located at [`wayland/cursor`](wayland/cursor) & [`wayland/cursor/xcursor`](wayland/cursor/xcursor)
+respectively.
+
+To demonstrate the functionality of this module
+[`examples/imageviewer`](examples/imageviewer) contains a simple image
+viewer. It demos displaying a top-level window, resizing of window,
+cursor themes, pointer and keyboard. Because it's in pure Go, it can be
+compiled without CGO. You can try it using the following commands:
+
+```sh
+CGO_ENABLED=0 go install github.com/AvengeMedia/DankMaterialShell/core/pkg/go-wayland/examples/imageviewer@latest
+
+imageviewer file.jpg
+```
