+# Contributing to Aqloss
+
+Thanks for wanting to contribute. Here's what you need to know.
+
+## Project structure
+
+```
+lib/                → Flutter frontend (Dart)
+rust/src/           → Audio backend (Rust)
+  audio_engine.rs   → playback core
+  discord_rpc.rs    → Discord rich presence
+  api.rs            → bridge between Rust and Flutter
+```
+
+## Getting started
+
+1. Make sure you have Flutter and Rust installed
+2. Fork the repo and clone your fork
+3. Run `flutter pub get` in the root
+4. Run `cargo build` inside `rust/`
+5. Start the app with `flutter run`
+
+## Before submitting a PR
+
+- Keep changes focused — one fix or feature per PR
+- If you're fixing a bug, mention the issue number (`Fixes #123`)
+- Test on your platform at minimum; note if you can't test others
+- For Rust changes, make sure there are no new `unwrap()`/`expect()` on hot paths — use `?` or `global_opt()` instead
+- For Flutter changes, test both desktop and mobile behavior if relevant (they can differ, e.g. context menus)
+- Short commit messages are fine, just be descriptive enough
+
+## Code style
+
+- Rust: `cargo fmt` before committing
+- Dart: `dart format .` before committing
+- Comments are welcome but keep them brief — `// ...` style, not paragraph essays
+
+## What to work on
+
+Check issues labeled `good first issue` or `help wanted`. If you want to work on something, leave a comment first so we don't duplicate effort.
+
+## Reporting bugs
+
+Use the bug report template. Logs are really helpful — especially backend logs and `RUST_BACKTRACE=1` output for panics.
