+*** IMPORTANT NOTICE FOR 7.6 UPGRADES ***
 
+Be sure to read the version specific upgrade information before proceeding:
+https://our.umbraco.org/documentation/Getting-Started/Setup/Upgrading/version-specific#version-7-6-0
+
+You will most likely need to make some changes to your web.config and you will need to be 
+aware of the breaking changes listed there to see if these affect your installation.
+
+
+Don't forget to build!
 
 We've done our best to transform your configuration files but in case something is not quite right: remember we
 backed up your files in App_Data\NuGetBackup so you can find the original files before they were transformed.
