-# Contributing to CC: Tweaked
-As with many open source projects, CC: Tweaked thrives on contributions from other people! This document (hopefully)
-provides an introduction as to how to get started in helping out.
-
-If you've any other questions, [just ask the community][community] or [open an issue][new-issue].
-
-## Reporting issues
-If you have a bug, suggestion, or other feedback, the best thing to do is [file an issue][new-issue]. When doing so,
-do use the issue templates - they provide a useful hint on what information to provide.
-
-## Developing
-In order to develop CC: Tweaked, you'll need to download the source code and then run it. This is a pretty simple
-process.
-
- - **Clone the repository:** `git clone https://github.com/SquidDev-CC/CC-Tweaked.git && cd CC-Tweaked`
- - **Setup Forge:** `./gradlew setupDecompWorkspace`
- - **Run Minecraft:** `./gradlew runClient` (or run the `GradleStart` class from your IDE).
-
-If you want to run CC:T in a normal Minecraft instance, run `./gradlew build` and copy the `.jar` from `build/libs`.
-These commands may take a few minutes to run the first time, as the environment is set up, but should be much faster
-afterwards.
-
-### Code linters
-CC: Tweaked uses a couple of "linters" on its source code, to enforce a consistent style across the project. While these
-are run whenever you submit a PR, it's often useful to run this before committing.
-
- - **[Checkstyle]:** Checks Java code to ensure it is consistently formatted. This can be run with `./gradlew build` or
-   `./gradle check`.
- - **[illuaminate]:** Checks Lua code for semantic and styleistic issues. See [the usage section][illuaminate-usage] for
-   how to download and run it.
-
-[new-issue]: https://github.com/SquidDev-CC/CC-Tweaked/issues/new/choose "Create a new issue"
-[community]: README.md#Community "Get in touch with the community."

 I'd generally recommend you don't contact me directly (email, DM, etc...) unless absolutely necessary (i.e. in order to
 report exploits). You'll get a far quicker response if you ask the whole community!
