-Username => Dossier
+TL;DR: Username => Dossier
+
+Maigret is designed to gather all the available information about person by his usernname.
+
+What kind of information is this? First, links to person accounts. Secondly, all the machine-extractable
+pieces of info, such as: other usernames, full name, URLs to people's images, birthday, location (country,
+city, etc.), gender.
+
+All this infromations forms some dossier, but it also useful for other tools and analytical purposes.
+Each collected piece of data has a label of a certain format (for exa,ple, ``follower_count`` for the number
+of subscribers or ``created_at`` for account creation time) so that it can be parsed and analyzed by various
+systems and stored in databases.
