 ## Contributing
+As long as it's not linux/cross-platform skeleton/compatibility layer, all of the code on the repo that's not behind a preprocessor condition(like FIX_BUGS) are **completely** reversed code from original binaries.

+We **don't** accept custom codes, as long as it's not wrapped via preprocessor conditions, or it's linux/cross-platform skeleton/compatibility layer.

+We accept only these kinds of PRs;

+- A new feature that exists in at least one of the GTAs (if it wasn't in III/VC then it doesn't have to be decompilation)  
+- Game, UI or UX bug fixes (if it's a fix to original code, it should be behind FIX_BUGS)
+- Platform-specific and/or unused code that's not been reversed yet
+- Makes reversed code more understandable/accurate, as in "which code would produce this assembly".
+- A new cross-platform skeleton/compatibility layer, or improvements to them
+- Translation fixes, for languages original game supported
+- Code that increase maintainability  
+
 We have a [Coding Style](https://github.com/GTAmodding/re3/blob/master/CODING_STYLE.md) document that isn't followed or enforced very well.
 
 Do not use features from C++11 or later.
