 ## 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.
+It uses vagrant to accomplish this and create a locally available target host.
 Install [vagrant](https://www.vagrantup.com/) on your system and to make tests repeatable also install the vagrant plugins `vagrant-hosts` and `vagrant-hostsupdater`,
 which will set a static IP for the vagrant host to be reachable under.

+Additionally, since the test setup mirrors the production setup in that it makes use of subdomains for the individual hosted applications,
+the server needs to be reachable under a domain name, 
+not just an IP address.
+For now this is most simply accomplished through editing the hosts file, e.g.:
+
+```hosts
+192.168.56.2 ansible.test
+192.168.56.2 git.ansible.test
+192.168.56.2 links.ansible.test
+```
+
+This will allow you to reach the main domain under `http(s)://ansible.test` and sets up two subdomains that can be reached.
+Be aware that the hosts file does not support subdomain wildcards. 
+You will have to specify each hostname individually or use a tool such as `dnsmasq`. 
+Read more [here](https://serverfault.com/questions/118378/in-my-etc-hosts-file-on-linux-osx-how-do-i-do-a-wildcard-subdomain).
+
 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,
