 requests to the project. *We're usually pretty lenient with pull requests, but this guide will help
 make the process go more smoothly.*
 
+### Acceptable Pull Requests
+
+**Bug fixes** and **new features** are welcome. However, some things like heuristic-based checks
+will **not** be accepted.
+
 ### Pull Request Guidelines
 
-- **Compatibility**
-  - Any changes must be compatible with
-  the [supported environments](https://github.com/GrimAnticheat/Grim/wiki/Supported-environments) (Spigot, Paper, Folia, Fabric, etc.)
-  - The plugin must be compatible with minecraft versions 1.8 and higher. Exempting checks from specific versions is acceptable.
-  - The plugin must be able to run on Java 17 or higher. Changes that don't support Java 17 at runtime will not be accepted.
-
-- **Non-acceptable pull requests**
-  - Heuristic-based checks will not be accepted; however, basic rate limiting such as blocking attacks based on CPS is acceptable.
-  - Checks that can be easily circumvented that don't block packets or fix anything are likely to not be accepted.
-  - Checks or features that are too specific to a single environment or minecraft version are likely to not be accepted.
-  - Changes that require large or unnecessary dependencies will likely not be accepted.
-
-- **Pull request formatting**
-  - Create a new branch for your feature or fix when forking the repository.
-  - Reference related issues in your pull request description if applicable.
-  - Write clear and descriptive commit messages.
-
-- **Code styling**
-  - Add code comments for complex logic or significant changes.
-  - Try to keep your code clean and avoid duplication.
-  - Thoroughly test your changes before submitting your pull request.
