-# Ajenti plugin template
+# Ajenti plugin DNS API
 
-This is the plugin template used by ajenti-dev-multitool
+This plugin is attented to give an access to an external registrar API, like Gandi or GoDaddy, and manage the DNS entries.
+Currently, there's only one [provider for the Gandi API](https://github.com/ajenti/ajenti/blob/master/plugins/dns_api/providers/gandi.py), but feel free to write your own provider for your registrar API.
+The code should be enough commented to understand how it works.
+
+## Configuration for the Gandi API
+
+Just add the following entries in `/etc/ajenti/config.yml`:
+
+```
+dns_api:
+  provider: gandi
+  apikey: YOUR_API_KEY
+```
+
+and then restart `Ajenti`.
