+    git clone git@github.com:petaflot/pygcode.git --depth=1
     cd pygcode
     pip install -e .

+## Configuration
+
+Make sure you set `_DEFAULT_` to the dialect you want to use in `src/pygcode/dialects/__init__.py` ; this is absolutely suboptimal, contributions are welcome. Also, note that `marlin2` flavor covers all versions of Marlin ; due to some functional redundances, some commands have been commented out (typically for bed leveling and delta bots, see `src/pygcode/gcodes_marlin.py`).
