  git status

  # git stash

  # git restore

  ```

- [ ] Checkout current deployed state as `revert` branch with:

  ```bash

  # on web01.ecloud.global and web02.ecloud.global

  # on /mnt/repo-base/user-documentation/

  git branch -D revert

  git branch revert

  ```

### Deployment procedure

  ```bash

  # on web01.ecloud.global and web02.ecloud.global
