+# docker-wayland-x-gui
+
+This repository provides a reference setup to enable graphical applications (Wayland, X11, or XWayland) to be displayed on the host's compositor/display server. It also includes PipeWire and ALSA connections/pass-through for audio support.
+
+## Features
+
+* **Wayland, X11, and XWayland** app support
+* **PipeWire** and **ALSA** integration for sound
+* Launch GUI apps from a Docker container directly on your host display
+* Configurable **UID/GID** and mount paths to match your host environment
+
+## Prerequisites
+
+* Docker installed and configured
+* A Wayland-compatible host compositor (e.g., Sway, GNOME Shell, KDE, etc.)
+* PipeWire and/or ALSA installed and running on the host
+
+## Configuration Notes
+
+Depending on your system setup, you may need to adjust:
+
+* Mount paths for Wayland/X11 sockets, sound devices, and config directories
+* UID/GID inside the container to match your host user
+
+By default:
+
+* **UID:** `1000`
+* **GID:** `100`
+
+These can be overridden using environment variables.
+
+## Usage
+
+You can launch apps from the host system into the running container using:
+
+```bash
+docker exec <container-name> <app>
+```
