+When `deploy.dotenv` config option is set to TRUE, some options can be ommitted and they will be loaded from following ENV variables instead:
+- `HEXO_RSYNC_HOST` -> maps to `deploy.host`
+- `HEXO_RSYNC_PORT` -> maps to `deploy.port`
+- `HEXO_RSYNC_USER` -> maps to `deploy.user`
+- `HEXO_RSYNC_ROOT` -> maps to `deploy.root`
+
+This can be useful in a situation when you do not want to store your SSH details in the repository, but load them from your deployment environment.
