+    ```
+
+   Or activate [direnv](https://direnv.net/) to automatically enter the nix shell.
+   It is recommended to use [nix-direnv](https://github.com/nix-community/nix-direnv).
+   If your system ships outdated bash, [install direnv](https://direnv.net/docs/installation.html) via package manager.
+   Additionally, you may want to add the [vscode extension](https://github.com/direnv/direnv-vscode).
+
+   ```sh
+   direnv allow
+   ```
+
+3. Execute and follow instructions of
+
+    ```sh
+    just onboard
+    ```
