+## The `sync` command
+
+You can use `slate sync` to synchronize your slates. There's no default configuration for this command, you'll have to create the file `~/.config/slate/config.toml` and add your sync command, for example:
+
+```toml
+sync = "git add . && git commit -m 'Update slates'; git pull --rebase origin master && git push origin master"
+```
+
+This would stage & commit every updates in `~/.config/slate/`, update your local copy and push your updates to the `origin` remote.
