 A useful command is `pip-sync requirements/dev.txt`, it uninstalls packages
 from your virtualenv that aren't explicitly specified as dependencies.

+These are not strictly necessary but very convenient.
+
+### Direnv (automatic venv)
+
+When direnv is [integrated into the shell](https://direnv.net/docs/hook.html)
+entering the project directory for the first time will cause direnv to create a
+hidden directory for the virtual environment.

+It will also activate that existing virtualenv automatically upon entering the

+If your editor spawns a shell window or new terminal, it might be necessary to
