 Please see [Loop and Learn: Loop Follow](https://www.loopandlearn.org/loop-follow/) for all the building options.
 
+With the release of version 2.1.0, there is now an easy option for building up to three instances of the Loop Follow app for multiple Loopers in your family. Each instance can be configured to have the display name you choose with these names being the default:
+
+* LoopFollow
+* LoopFollow_Second
+* LoopFollow_Third
+
+#### Display Name Updates
+
+The _display_name_ is found in a single file.
+
+* Suggestion if you customize the name: use LF {unique name} so you can find the apps easily in iOS Settings screen
+
+Summary instructions by build method:
+
+* Browser Build: 
+    * Commit the desired _display_name_ in the LoopFollowDisplayNameConfig.xcconfig file of your forked repository for LoopFollow, LoopFollow_Second or LoopFollow_Third
+* Mac-Xcode Build
+    * First build with script, you will be prompted to enter the desired _display_name_
+    * This _display_name_ is used each time you select a fresh download for LoopFollow 1, 2 or 3
+    * To modify the _display_name_ for subsequent script builds, edit the appropriate file in the ~/Downloads/BuildLoopFollow folder
+        *  LoopFollowDisplayNameConfig.xcconfig 
+        *  LoopFollowDisplayNameConfig_Second.xcconfig 
+        *  LoopFollowDisplayNameConfig_Third.xcconfig 
+
+#### Updates
+
+When modifications and versions are updated, there might be a slight delay for getting the second and third forks updated as well, so if you are using this feature, wait until all three repositories are updated.
