 ```bash
 cargo build
 ```
-The latest stable server is automatically built to an appimage at https://github.com/StardustXR/server/releases for easy testing.
 
-## Usage
+## Install
-
+```bash
-First, try running `cargo run` in a terminal window. If a headset is plugged in and OpenXR is working no window will show up. However, the headset should show the same things as the window that opens:
+cargo install
-
+```
-![A pitch black void with a single bleach white hand in the middle](/img/xr_mode_windowed_blank.png)
-
-Stardust won't do anything interesting without clients! Try some from https://github.com/StardustXR.
-
-### Default Sky
-
-You can set a default skytex/skylight by putting your favorite HDRI equirectangular sky in `~/.config/stardust/skytex.hdr`. Certain clients can override this.
-
-Flatscreen mode when the default skybox is [Zhengyang Gate](https://polyhaven.com/a/zhengyang_gate):
-![A pitch black window representing Stardust in flatscreen mode](/img/flatscreen_3.png)
-
-### Windowed Mode
-
-If the stardust server can't connect to an OpenXR runtime or you force it into flatscreen mode with `-f`, the server will show in a window.
-![A black void representing Stardust in XR mode with a hand skeleton in the middle](/img/flatscreen_2.png)
-
-You can navigate around by right click + dragging to look around, Shift+W/A/S/D/Q/E to move. If you have a virtual hand, left click pinches, right click points, both make a fist.
-
-### Flags
-#### Flatscreen (-f)
-
-The server will show up in windowed mode no matter what with your mouse pointer being turned into a 3D pointer. Keyboard input will be sent to whatever your mouse is hovering over like visionOS simulator.
-Flatscreen mode upon initial startup:
-![A pitch black window representing Stardust in flatscreen mode](/img/flatscreen_1.png)
-
-#### Overlay (-o \<PRIORITY>)
-
-The server will, if in XR mode, be overlaid using the OpenXR overlay extension with the given priority.
-
-#### Disable controller (--disable-controller)
-
-Some runtimes such as Monado may emulate a controller using a hand, and this messes with Stardust's input system. Set this flag to ignore the controllers that the OpenXR runtime provides.
-
-#### Execute (-e </path/to/executable>)
-
-When wayland and OpenXR and such are initialized, run the given executable (such as a bash script) with all the environment variables needed to connect all clients of any type to the server. If not set, the server will run the executable at `~/.config/stardust/startup` if it exists. This is how stardust desktop environments can be made.
