The 2. point in the quick start guide is about the squads.excel file!
I think especially for beginners it will be better to explain which one of the excel files is ment, while there are 2 of them in the data ordner.
Everyone shouldn't/couldn't know what with "csv. file" means!
"Comma separated values"
Suggestion:The one with a on the symbol or something like that!! (I am not the expert for that!)
