 # iOS example
 
-----
 ## Introduction
 
 This example is the default XCode "OpenGL" example code, modified to support ImGui and [Synergy](http://synergy-project.org/). 
 
+It is a rather complex example because of all of the faff required to get an XCode/iOS application running. Refer to the regular OpenGL examples if you want to learn about integrating ImGui.
+
 Synergy (remote keyboard/mouse) is not required, but it's pretty hard to use ImGui without it. Synergy includes a "uSynergy" library that allows embedding a synergy client, this is what is used here. ImGui supports "TouchPadding", and this is enabled when Synergy is not active.
 
 ## How to Use
-----
 
 0. In Synergy, go to Preferences, and uncheck "Use SSL encryption"
 0. Run the example app.

 ImGui is a c++ library. If you want to include it directly, rename your Obj-C file to have the ".mm" extension.
