+# Project conventions
+
+## Before committing
+
+Always run `cargo test` and verify all tests pass before committing.
+Never skip this step, even for small or "obvious" changes.
+
+## Rust conventions
+
+- Use `fs_err` instead of `std::fs` (enforced by clippy)
+- Use miette's `bail!` and `ensure!` macros instead of `return Err(miette!(...))`
+- Prefer `for` loops over `Iterator::for_each` for side-effects (enforced by clippy)
