+
+Possible CLI options:
+
+- use the **--client-credentials-file** option to change the filename in which the client credentials are stored (defaults to feed2toot_clientcred.txt)
+- use the **--user-credentials-file** option to change the filename in which the user credentials are stored (defaults to feed2toot_usercred.txt)
+- use the **--name** to change the Mastodon app name (defaults to feed2toot)
+
+Example with full options and full output::
+
+    $ ./register_feed2toot_app --user-credentials-file f2tusercreds.txt --client-credentials-file f2tclientcreds.txt --name f2t
+    
+    This script generates the Mastodon application credentials for Feed2toot.
