-# Stardust XR Server
+# Stardust XR Reference Server
 
-Stardust XR is a display server for VR and AR headsets on Linux-based systems. [Stardust provides a 3D environment](https://www.youtube.com/watch?v=v2WblwbaLaA), where anything from 2D windows (including your existing apps!), to 3D apps built from objects, can exist together in physical space.  
+This project is a usable Linux display server that reinvents human-computer interaction for all kinds of XR, from putting 2D/XR apps into various 3D shells for varying uses to SDF-based interaction.

+2. CMake
+3. EGL+GLES 3.2
+4. GLX+Xlib
+5. fontconfig
+6. dlopen

-## Installation
-
-More detailed instructions and walkthroughs are provided at https://www.stardustxr.org
-
-The [Terra Repository](https://terra.fyralabs.com/) is required, and comes pre-installed with [Ultramarine Linux](https://ultramarine-linux.org/). Other Fedora Editions and derivatives can directly install terra-release:
-
-```bash
-sudo dnf install --nogpgcheck --repofrompath 'terra,https://repos.fyralabs.com/terra$releasever' terra-release
-```
-
-For a full installation of the Stardust XR server *and* a selected group of clients, run:
-
-```bash
-sudo dnf group install stardust-xr
-```
-
-## Manual Build
-We've provided a manual installation script [here](https://github.com/cyberneticmelon/usefulscripts/blob/main/stardustxr_setup.sh) that clones and builds the Stardust XR server along with a number of other clients from their respective repositories, and provides a startup script for automatically launching some clients.
-
-After cloning the repository
+## Build
 ```bash
 cargo build
 ```
+The latest stable server is automatically built to an appimage at https://github.com/StardustXR/server/releases for easy testing.
 
 ## Usage
-> [!NOTE]
-> For help with setting up an XR headset on linux, visit https://stardustxr.org/docs/get-started/setup-openxr
 
+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:
 
-The **Stardust XR Server** is a server that runs clients, so without any running, you will see a black screen. If you only have the server installed, we recommend also cloning and building the following clients to start: [Flatland](https://github.com/StardustXR/flatland), which allows normal 2D apps to run in Stardust, [Protostar](https://github.com/StardustXR/protostar), which contains Hexagon Launcher, an app launcher menu, and [Black Hole](https://github.com/StardustXR/black-hole) to quickly tuck away your objects and apps (kind of like desktop peek on Windows).
+![A pitch black void with a single bleach white hand in the middle](/img/xr_mode_windowed_blank.png)
 
-First, try running `cargo run -- -f` in a terminal window to check out flatscreen mode, (or `stardust-xr-server -f` / `stardust-xr-server_dev -f` if you installed via dnf or the manual installation script, respectively, as they provide symlinks.)
+Stardust won't do anything interesting without clients! Try some from https://github.com/StardustXR.
 
-If there aren't already any clients running, you'll need to manually launch them by either navigating to their repositories and running `cargo run`, or running them via their names if you installed via dnf or the manual installation script, such as `flatland`, `hexagon_launcher`, etc.
+### Default Sky
 
-> [!IMPORTANT]
-> [Flatland](https://github.com/StardustXR/flatland) must be running for 2D apps to launch. 
+You can set a default skytex/skylight by putting your favorite HDRI equirectangular sky in `~/.config/stardust/skytex.hdr`. Certain clients can override this.
 
-### Startup Script
-A startup script can be created at `~/.config/stardust/startup` that will launch specified settings and clients/applications, an example of which is shown [here](https://github.com/cyberneticmelon/usefulscripts/blob/main/startup). If you used the [installation script](https://github.com/cyberneticmelon/usefulscripts/blob/main/stardustxr_setup.sh), one will have already been made for you. This allows wide flexibility of what clients to launch upon startup (and, for example, *where*, using the [Gravity](https://github.com/StardustXR/gravity) client to specify X Y and Z co-ordinates).
+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)
 
-### Flatscreen Navigation
-A video guide showcasing flatscreen controls is available [here](https://www.youtube.com/watch?v=JCYecSlKlDI)  
+### Windowed Mode
 
-To move around, hold down `Shift + W A S D`, with `Q` for moving down and `E` for moving up.
-![wasd](https://github.com/StardustXR/website/blob/main/static/img/updated_flat_wasd.GIF)
+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)
 
-To look around, hold down `Shift + Right` Click while moving the mouse. 
-![updated_look](https://github.com/StardustXR/website/blob/main/static/img/updated_flat_look.GIF)
+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.
 
-To drag applications out of the app launcher, hold down `Shift + ~`
-![updated_drag](https://github.com/StardustXR/website/blob/main/static/img/updated_flat_drag.GIF)
+### Flags
+#### Flatscreen (-f)
 
-### XR Navigation
-A video guide showcasing XR controls is available [here](https://www.youtube.com/watch?v=RbxFq6JjliA)  
+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)
 
-**Quest 3 Hand tracking**:
-Pinch to drag and drop, grasp with full hand for grabbing, point and click with pointer finger to click or pinch from a distance  
+#### Overlay (-o \<PRIORITY>)
 
-![hand_pinching](https://github.com/StardustXR/website/blob/main/static/img/hand_pinching.GIF)
+The server will, if in XR mode, be overlaid using the OpenXR overlay extension with the given priority.
 
-**Quest 3 Controller**:
-Grab with the grip buttons, click by touching the tip of the cones or by using the trigger from a distance  
+#### Disable controller (--disable-controller)
 
-![controller_click](https://github.com/StardustXR/website/blob/main/static/img/controller_click.GIF)
+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.
+
+#### Help (-h, --help)
+

+
+## Test
+
+##### Gnome Graphical Integration Test
+
+- `nix build .#gnome-graphical-test`
+
+   This test uses Nix to reproducibly execute a QEMU virtual machine which
+   spawns a full Gnome desktop. It runs `monado-service`, `stardust-xr-server`
+   `flatland` underneath of Gnome and then attaches `weston-cliptest` to the
+   `flatland` process running underneath of `stardust-xr-server`, the result is
+   a screenshot in PNG format that should look like expected. If any process in
+   this test produces an exit code above 0, the test will fail, graphical bugs
+   should be visible in the screenshot. An example of the result is below.
+
+   ###### Result
+
+   ![image](https://github.com/StardustXR/server/assets/26458780/e21cd039-2528-4568-b20a-ce4abfab6d9b)
+
+##### Everything
+
+`nix flake check` will build every test underneath of the `checks` attribute in the `flake.nix`
