+# Menu Shaders
+Replaces the background of the main menu with a customizable shader.
+
+This is a port of mat's [Menu Shaders](https://github.com/matcool/small-gd-mods/blob/3e1783c7e281cbbccd53f9c4ceb697d5a6f839dd/src/menu-shaders.cpp) mod.
+
+## Usage
+To change the shader, create a texture pack with a file called menu-shader.fsh.
+
+For a few already made shaders, check out this ~~Twitter~~ X [thread](https://twitter.com/mateus44_/status/1412108556921344006?s=20).
+
+This mod also supports some Shadertoy shaders, to use them:
+1. Find a shader you want to use on [Shadertoy](https://shadertoy.com)
+2. Copy/paste the code on the right into your menu-shader.fsh
+3. If you see the default GD background and errors from Menu Shaders in the console, that likely means that the shader you want to use is incompatible.
+
+## Advanced Usage
+
+### New shader locations
+You can also replace shaders in `cgytrus.menu-shaders/any-frag.glsl` and `any-vert.glsl`
+for the fragment and vertex shaders respectively,
+where `any` can be replaced with either `main`, `level-select`, `creator`, `level-browser`,
+`edit-level`, `play-level`, `search`, `garage`, `leaderboards`,
+`gauntlets`, `gauntlet` or `treasure-room` to override the shader only for the respective menu.
+
+Shadertoy compatibility is disabled in these shaders.
+
+### Sprites
+You can use sprites from resources (including custom ones) by adding a comment starting with `//@`
+followed by sprite names separated by commas.
+
+Each sprite in the list will add a `sampler2d` uniform called `sprite0`,
+where `0` is the index of the sprite in the list.
+
+### Nodes
+You can get information about nodes in the scene by adding a comment starting with `//#`
+followed by node IDs separated by commas.
+
+Each node in the list will add a few uniforms, where `0` is the index of the sprite in the list:
+- `vec2 node0Pos` - node position in cocos points in world space
+- `float node0Rot` - node rotation in degrees in world space
+- `vec2 node0Scale` - node scale in world space
+- `vec2 node0Size` - node content size in cocos points in world space
+- `bool node0Visible` - node visibility (whether it's drawn or not)
