-## Guidelines
+## Tips
 
 - Formatting uses [Biome](https://biomejs.dev/). Make sure there are no warnings or errors before submitting a PR.
 
-- Keep PRs small and focused.
-
 - We prefer conventional commits, but they are not enforced. See [here](https://www.conventionalcommits.org/en/v1.0.0/) for reference.
 
 - No AI-generated code please. AI autocomplete is fine, but not fully AI code. If you submit AI-generated code without making it clear, it may be rejected.
 
 - Type files are auto-generated from JSDoc comments
 
-- For optimizations, please always publish a benchmark of the before/after difference before submitting a PR, ideally including your device specs. RAM/CPU usage is also appreciated.
 
-Maintainers may reject PRs at their discretion if they don't follow these guidelines or don't align with the project's goals.
+## Code of Conduct
+
+* Be respectful to others. Please keep unstructured critique to a minimum. If you have solid ideas you want to experiment with, make a fork and see how it works.
+
+* Any spamming, trolling, flaming, or baiting is not welcome.
+
+* Keep contributions constructive and in good faith.
