+## Deployment
+
+Agaric is currently using a Platform as a Service version of Drutopia with additional modules.
+
+Set up [drutopia_host](https://gitlab.com/drutopia-platform/drutopia_host) and [hosting_private](https://gitlab.com/drutopia-platform/hosting_private), as documented in hosting private.
+
+Then use [ahoy]().
+
+If Agaric's Drutopia PaaS base has changed (the composer.lock in this directory), produce and push a new build: 
+
+```
+ahoy deploy-build agaric
+```
+
+To deploy everything else (config, templates, styles):
+
+```
+ahoy deploy-site agaric_live
+```
