+Upgrading from Drupal 7
+-----------------------
+
+This module is the successor to the [Drupal 7 Profile2
+module](https://drupal.org/project/profile2) and will automatically import and
+convert any Profile2 profiles when upgrading from a Drupal 7 installation.
+
+Note that this module does NOT import from the [deprecated Profile
+module](https://www.drupal.org/node/874026) that was provided in Drupal 7 core
+as an upgrade path from Drupal 6 sites that used Profiles. If you have profiles
+from the Drupal 7 Profile module, you should either convert them to Profile2
+profiles in Drupal 7 prior to upgrading to Backdrop, or recreate them in
+Backdrop after you upgrade.
