+# Installation
+
+The `roverlib-python` library comes installed by default on every Rover, but if for some reason it isn't, [ssh into the rover](https://ase.vu.nl/docs/tutorials/Fundamental%20Concepts/connecting) and run the following pip install command:
+
+``` bash
+# Install the latest version
+pip install roverlib
+# Install a specific version
+pip install roverlib==1.2.3
+```
+
+Using the same commands, you can update or downgrade `roverlib-pyton` globally on the Rover. All available versions that can be installed can be found [here](https://pypi.org/project/roverlib/#history).
