+### Push

+Note: Push is currently only available as a Docker Command
+
+```bash
+docker run --env OUTLINE_BASE_URI="https://kb.example.com" \
+           --env OUTLINE_TOKEN="PUT YOUR TOKEN HERE" \
+           --env OUTLINE_TOKEN="PUT YOUR TOKEN HERE" \

+```

 #### Limitations
 
 - Images are currently not imported. Host them externally for this to work.
 - Only `.md` files are currently supported
+- `push` doesn't sync file-history, but is meant to push a one-time backup to Git.
+- `StrictHostKeyChecking` is currently disabled for `push`, please only run this in trusted networks.
