 # Jay
 
-Jay is a Wayland compositor written and configured in the rust programming
-language with hot-reload support. Jay offers improved flexibility,
-configurability, stability, and performance.
+Jay is a Wayland compositor.

-## Status
+## Features
 
-Jay is beta-quality software. For many people it should be possible to use Jay for most
-of their work. Jay has a small integration test suite but sometimes there are regressions
-that cause features to break. I'm currently looking for people willing to test Jay,
-especially on Nvidia hardware.
-
-### Working Features
-
-The following features have been implemented and should work:
-
-- Tiling windows
-- Floating windows
-- Fullscreen
-- Multiple workspaces
-- Multiple monitors
-- Copy/paste including middle-click paste
-- Screenshots
-- Screencasting
-- Keyboard shortcuts
-- Theming
-- Configuration reload
-- XWayland
-- Screensaver (paused during video playback)
-- Notifications (via mako)
-- Video playback with synced audio (via presentation time)
-- Simple games that don't require cursor grabs
-- GPU reset recovery
-- Screen locking
-- Monitor hotplug
-- Fractional scaling
-- Hardware cursors
-- Pointer constraints
-- Selecting the primary device in multi-GPU systems 
-- An OpenGL backend
-- A Vulkan backend
-- Explicit sync
-
-### Missing Features
-
-The following features are known to be missing or broken and will be implemented
-later:
-
-- Touch and tablet support
-- Damage tracking (any kind of damage causes a complete re-render currently)
-
-## Native library dependencies
-
-Jay is written in rust and will fetch all of its rust dependencies
-automatically. It is however unavoidable that Jay depends on a number of native
-libraries:
-
-* **libinput.so**: For input event processing.
-* **libgbm.so**: For graphics buffer allocation.
-* **libxkbcommon.so**: For keymap handling.
-* **libudev.so**: For device enumeration and hotplug support.
-* **libpangocairo-1.0.so**: For text rendering.
-
-These libraries are usually available on any Wayland-capable system.
-
-## Runtime dependencies
-
-At runtime, Jay depends on the following services being available on the system:
-
-* **An up-to-date linux kernel and graphics drivers**: Jay makes aggressive use
-  of linux features and might not work on older systems.
-* **XWayland**: For XWayland support.
-* **Pipewire**: For screencasting.
-* **A running X server**: For the X backend. (Only required if you want to run
-  Jay as an X client.)
-* **Logind**: For the metal backend. (Only required if you want to run Jay from
-  a TTY.)
-* **libEGL.so**, **libGLESv2.so**: For the OpenGL backend.
-* **libvulkan.so**: For the Vulkan backend.
-
-## Building and Installing
-
-Install the latest stable version of rustc and cargo. Follow the instructions on
-https://rustup.rs or use the packages provided by your distribution. Note that
-only the latest stable version is supported.
-
-You can now build Jay using this command:
-```sh
-cargo build --release
-```
-The resulting binary will be located at `./target/release/jay`.
-
-Alternatively, cargo can also install the binary for you:
-```sh
-cargo install --path .
-```
-This will install the binary at `$HOME/.cargo/bin/jay`. If you have not already
-done so, you can add `$HOME/.cargo/bin` to your path.
-
-## Running
-
-You can run Jay as a freestanding compositor or as an application under X.
-
-To start Jay as a freestanding compositor switch to a virtual terminal by
-pressing `CTRL-ALT-F2` (or F3, F4, ...) and run
-```sh
-jay run
-```
-
-To start Jay as an X application, execute the same command from a terminal
-emulator under X.
-
-Before running Jay as a freestanding compositor, you might want to familiarize
-yourself with the [default keyboard shortcuts][shortcuts]. In particular, you
-can quit Jay by typing `ALT-q`.
-
-[shortcuts]: ./default-config/src/lib.rs
+See [features.md](./docs/features.md).
 
 ## Configuration
 
-Jay is configured using a shared library. A good starting point for your own
-configuration is the [default config crate][default].
+See [config.md](./docs/config.md).
 
-[default]: ./default-config
+## Building and Setup
 
-1. Copy this crate to a new directory.
-2. In `Cargo.toml`
-    - Update the path dependency to point to the correct directory.
-    - Change the name of the crate to `my-jay-config`.
-3. Make a useful change to `lib.rs`.
-4. Build the crate with `cargo build`.
-5. Move `target/debug/libmy_jay_config.so` to `$HOME/.config/jay/config.so`.
-
-When you start Jay, you will be able to make use of your useful change. At
-runtime you can repeat steps 3 to 5 and reload the configuration. By default,
-the shortcut to reload the configuration is `ALT-r`.
-
-If you want to see a more elaborate configuration, take a look at [my personal
-configuration][personal].

-
-## Screensharing
-
-Jay supports [xdg-desktop-portal-wlr][xdpw] but Jay is not currently listed in
-xdg-desktop-portal-wlr's wlr.portal file. To get screensharing to work, you have
-to manually edit `/usr/share/xdg-desktop-portal/portals/wlr.portal` and add
-`jay` to the `UseIn` list.
-
-In the future, Jay will provide a desktop portal itself.
