-CouchDB schema migration to Soledad 0.8.2
-=========================================
+CouchDB schema migration script: from soledad-server < 0.9.0 to >= 0.9.0
+========================================================================
 
-Migrate couch database schema from <= 0.8.1 version to 0.8.2 version.
+Starting with Soledad Server 0.9.0, the CouchDB database schema was changed to
+improve speed of the server side storage backend. Because of that, this script
+has to be run for all Leap providers that used to provide email using Soledad
+Server < 0.9.0.
+
+If you never provided email with Leap, you don't need to run this script.
