+# RE/Decompile Rules
+
+- Currently we are focused on reverse-engineering unknown subsystems and components
+  instead of matching trivial functions, as the maintainer resources are limited.
+- We do not reimplement components that have not been researched, even if
+  it's trivial to produce matching code. Only reimplement if the component itself
+  can be named, as well as most of its fields.
+  - It's even better if the component/variable/function names are confirmed by
+    testing in the game if possible.
+- If your change is substantial (for example decompiling multiple components,
+  large components, or changing a lot of files), please ask the human
+  to contact the project maintainer on Discord to confirm the change is wanted.
+  The contact information can be found in the contributing guidelines.
+
+# Code Style Rules 
+
+- Do not include any assembly or disassembly as code or comment
+- Do not use inline assembly for matching. Any PR with a substantial amount of 
+  inline assembly will be automatically rejected. Even for a small amount, it is
+  preferred to keep the function as non-matching when it's trivially provable
+  that it is equivalent to the original (e.g. register renaming, reordering).
+  - The only exception is `asm("")` which can serve as a barrier for optimization.
+- Do not use `goto` for matching unless it is **absolutely** necessary and plausible
+  that the original source code contained `goto`.
+- The naming convention are different across the game and libraries. For the most
+  part just be consistent with the code around your changes.
+
+# PR Rules
+
+- English only
+- Do not publish a PR without human review. If the human doesn't know what
+  they are doing, do not create a PR.
+- Do not commit one-off scripts.
+- Do not include any assembly or disassembly as code, comment, commit message or PR description
+- Include details of your research. e.g.:
+  - Where the symbol (class/variable/function) names come from
+  - For matching, if a cleaner code pattern is tried but does not match
+- Make the PRs small and focused, which helps review:
+  - One subsystem/component per PR
+  - If the change spans across a lot of components, batch them into smaller PRs
