+# Most recipes can re-run automatically on file change by prepending "watch" to the command. For example: `just lint` runs linting once, `just watch lint` runs linting on file change.
+# Some commands:
+# just                          - Run test and linting once
+# just watch                    - Watch test and lint, re-run on filechange
+# just [watch] test [crate]     - Run tests on workspace or the specified crate, e.g. `just test` or `just watch test emulator-tracing`
+# just [watch] lint [crate]     - Run linting on workspace or the specified crate
+# just [watch] clean            - Clean the repo, removing all compiled and generated artifacts
