+you can ignore files with the following command: 
+
+git update-index --assume-unchanged path/to/instance.cfg
+
+^ git ignore can only ignore files that are not on the repo at all, it will not respect files that are on the repo and always track changes on them. 
+As a workaround you can instead use this local command that will make your local repo ignore all changes to a given file. 
+
+To get the relative path of a file for the command, don't bother writing it out by hand, just right click on the file in the github desktop application in there will be a relative file path option to copy from.
