+A simple game catalogue and play session tracker.
+
+# Development
+
+The project uses `pyenv` to manage installed Python versions.
+If you have `pyenv` installed, you can simply run:
+
+```
+make init
+```
+
+This will make sure the correct Python version is installed, and it will install all dependencies using `poetry`.
+Afterwards, you can start the development server using `make dev`.
