+Quick start
+===========
+
+After :doc:`installing Maigret <installation>`, you can begin searching by providing one or more usernames to look up:
+
+``maigret username1 username2 ...``
+
+Maigret will search for accounts with the specified usernames across a vast number of websites. It will provide you with a list 
+of URLs to any discovered accounts, along with relevant information extracted from those profiles.
+
+.. note::
+   Maigret will search for accounts on a huge number of sites,
+   and some of them may return false positive results. At the moment, we are working on autorepair mode to deliver 
+   the most accurate results. 
+   
+   If you experience many false positives, you can do the following:
+
+   - Install the last development version of Maigret from GitHub
+   - Run Maigret with ``--self-check`` flag and agree on disabling of problematic sites
