 <p align=center>Create image filters by writing shaders.</p>
+
+## Supported Platforms
+
+- Linux [tested]
+- Windows
+
+You can find the latest releases [here](https://github.com/ChaoticByte/GlitchApp/releases/latest).
+
+## Usage
+
+The application includes presets. You can use them as a starting-point to write your own filters.  
+Just load an image, apply a preset, edit the code and hit `F5` to see the changes.
+
+### Load additional images using the `//!load` directive
+
+```glsl
+//!load <name> <filepath>
+uniform sampler2D <name>;
+```
+
+With this you can load additional images into your shader.  
+Have a look at the `Mix` preset:
+
+```glsl
+shader_type canvas_item;
+
+//!load img2 ./icon.png
+uniform sampler2D img2: repeat_enable, filter_nearest;
+
+void fragment() {
+	COLOR = mix(COLOR, texture(img2, UV), .5);
+}
+```
