 ## Mastodon APIs
 
+This plugin depends on [Mastodon.py](https://github.com/halcy/Mastodon.py).
+
 In order to publish on Mastodon you need to enter in `publishconf.py` the following information:
 
-TODO
 ``` python
-MASTODON_CONSUMER_KEY = ''
-...
+MASTODON_BASE_URL = 'URL of your Mastodon instance. For example https://mastodon.social'
+MASTODON_USERNAME = 'Your username for Mastodon login'
+MASTODON_PASSWORD = 'You password for Mastodon login'
 ```
+There is no need to register an app in your Mastodon profile because *Pelican-toot* will do it for you!
 
-This plugin depends on [Mastodon.py](https://github.com/halcy/Mastodon.py).
+On every run *Pelican-toot* looks for a file called `pelicantoot_clientcred.secret` and - if it is not found - it gets in touch with Mastodon, creates an app called *PelicanToot* and writes API keys and other necessary information in this file.
+
+If you cancel this file *Pelican-toot* will create another app (this could be done in case of problem despite the fact Mastodon advise this is NOT a good behaviour since app should be created only once).
