+### Mod Compatibility
+
+Probably not compatible with mods that add items to the default item groups, however a compatibility layer is planned.
+
+### Missing Items
+
+I'm doing my best to include all items including new ones from 1.20, but I might miss some so please report them on the issues page or in my [Discord server](https://discord.gg/CWEApqJ6rc).

+
+## Developing & Contributing
+
+Development is mostly straight forward.
+
+### Setup
+
+> It is recommended that you install the [Minecraft Development](https://plugins.jetbrains.com/plugin/8327-minecraft-development) Plugin for IntelliJ IDEA.
+
+1. Clone the repository from your fork.
+2. Open the project.
+3. Run `gradle genSources` to generate the sources.
+4. You can start developing!
+
+### Git Commit Messages
+
+Please use [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) for your commit messages.
+
+### Git Branches
+
+You can use any branch you like except main. But it is recommended to use `dev/<feature>` if you add something new and `fix/<issue>` if you are fixing something related to an issue.
+
+### Opening a Pull Request
+
+When you start your development please open a draft pull request. This way we can see that someone is working on select feature/bug.
+
+> Make sure to mention related issues/pull requests in your pull request.
