 `abra` is a command-line tool for managing your own [Co-op Cloud](https://coopcloud.tech). It can provision new servers, create apps, deploy them, run backup and restore operations and a whole lot of other things. Please see [docs.coopcloud.tech](https://docs.coopcloud.tech) for more extensive documentation.
 
+## Quick install
+
+```bash
+curl https://install.abra.autonomic.zone | bash
+```
