+"""Mastodon_ is an open source alternative to large social media platforms like
+Twitter/X, Facebook, ...
+
+Since it's federated and self-hostable, there's a large amount of available
+instances, which can be chosen instead by modifying ``base_url``.
+
+We use their official API_ for searching, but unfortunately, their Search API_
+forbids pagination without OAuth.
+
+That's why we use tootfinder.ch for finding posts, which doesn't support searching
+for users, accounts or other types of content on Mastodon however.
