## How to Contribute
### Code
All contributions are welcome!
You can look at the [Projects](https://github.com/yshui/picom/projects) page, and see if there is anything that interests you. Or you can take a look at the [Issues](https://github.com/yshui/picom/issues).
New features you think should be included in picom, a fix for a bug you found - please open a PR!
### Non-code
You can take a look at the [Issues](https://github.com/yshui/picom/issues).
Even if you don't want to contribute code, you can still contribute by compiling and running this branch, and report any issue you can find.
Contributions to the documents and wiki are also appreciated.
Contributions to the documents and wiki will also be appreciated.
Even if you don't want to add anything to picom, you are still helping by compiling and running this branch, and report any issue you can find.
### Become a Collaborator
Becoming a collaborator of picom requires significant time commitment. You are expected to reply to issue reports, reviewing PRs, and sometimes fix bugs or implement new feature. You won't be able to push to the main branch directly, and all you code still has to go through code review.
If this sounds good to you, feel free to contact me.

*--window-shader-fg-rule* 'SHADER':'CONDITION'::
Specify GLSL fragment shader path for rendering window contents using patterns. Similar to *--opacity-rule*, arguments should be in the format of 'SHADER:CONDITION', e.g. "shader.frag:name = \'window\'". Leading and trailing whitespaces in 'SHADER' will be trimmed. If 'SHADER' is "default", then the default shader will be used for the matching windows. (This also unfortunately means you can't use a shader file named "default").

*--dithered-present*
Use higher precision during rendering, and apply dither when presenting the rendered screen. Reduces banding artifacts, but might cause performance degradation. Only works with OpenGL.
