-# This python script patches both the UnrealEngine and the
-# integration repositories.  It is necessary to do this before
-# trying to build integration or UnrealEngine.  If something
-# generated by this script gets overwritten, it is perfectly safe
-# to run this script again.
+# This python script builds integration from scratch.  That includes:
 #
-# Files generated:
+#   - Generating BuildConfiguration.xml in integration repository
+#   - Generating BuildConfiguration.xml in UnrealEngine repository
+#   - Hardwiring paths into Source/Integration/lpx-paths.hpp
+#   - Generating Integration.uproject
+#   - Generating Integration.code-workspace
+#   - Patching LogMacros.cpp in UnrealEngine repository
+#   - Running Setup.sh in the UnrealEngine repository
+#   - Building luprex
+#   - Building ShaderCompileWorker
+#   - Building integration
 #
-#   INTEGRATION/Saved/UnrealBuildTool/BuildConfiguration.xml
