 ### Profiles
 All profiles that you want to use with the Open CUE CLI must be in the iCUE `GameSdkEffects` directory.
 On Windows this is in the installation directory of iCUE `C:\Program Files (x86)\Corsair\CORSAIR iCUE Software\GameSdkEffects`.

+These profiles are just the exported files from iCUE profiles.
+When export profiles from iCUE only select "Lighting Effects" in the export settings.
+
+Profiles are grouped into games, this is because the SDK was designed for iCUE Game integration.
+So each subdirectory of `GameSdkEffects` represent a game and contains all it's profiles and a `priorities.cfg` file.
 
 ### Use own profiles/effects
-Directories in `GameSdkEffects` correspond to games, but the games must not exist.
+The subdirectories of `GameSdkEffects` correspond to games, but you can also create own subdirectories.
 If you want to add your own profiles/effects, create a new directory in the `GameSdkEffects` directory called `profiles`.
 Create a new text file named `priorities.cfg` in the `profiles` directory.
