+# Cloudserve infrastructure
+
+## Testing
+
+This repository comes with a test-ready setup to try out the complete site setup locally.
+It uses vagrant to accomplish this and create a pretend target host.
+So, install [vagrant](https://www.vagrantup.com/) on your system and to make tests repeatable also install the vagrant plugins `vagrant-hosts` and `vagrant-hostsupdater`.
+
+```bash
+vagrant plugin install vagrant-hosts vagrant-hostsupdater
+```
+
+Then you are ready to run the complete infrastructure setup locally, 
+simply by executing `ansible-playbook site.yml`.
+You can of course pick and choose what should be executed with host limits, tags, group variables, and so on,
+but this should provide an easy way to see if a) the playbook is working as intended and b) what it does is useful.
