 1. **Make a community example** and place it inside the `community` folder of the [examples repository][examples].
 2. **Add tests**. There only few tests in Pixel at the moment. Take a look at them and make some similar.
 3. **Add a small feature or an improvement**. Feel like some small feature is missing? Just make a PR. Be ready that I might reject it, though, if I don't find it particularly appealing.
