# Upgrade Guide
WARNING Always backup your `config.js`, `custom.css` and `modules`
folder before you start the upgrade process!
If you want to update your MagicMirror² to the latest version, use your terminal to go to your Magic Mirror folder and type the following command:
git pull && npm run install-mm
If you changed nothing more than the config or the modules, this should work without any problems.
WARNING Using `git reset --hard` as described below will delete all
your changes made in the source code, so only execute this if you know what you are doing!
git status to see your changes, if there are any, you can reset them with
git reset --hard. After that,
git pull should be possible.
