Setup & documentation

My first installed and used flatpak app. I tried to setup it for go development with calling exiftool from within the code.

First problem: Go command is not found.
Solved by adding --env=PATH=/app/bin:/usr/bin:/run/host/usr/lib/golang/bin in /var/lib/flatpak/app/com.visualstudio.code/current/active/export/share/applications/com.visualstudio.code.desktop
Not sure if it is a good solution of if there is any recommended way how to solve this. Anyway, in my opinion there is not enough documentation available.

Next problem: 'exiftool somefile.mp4' failed with Can't locate Image/ExifTool.pm in @INC
So probably something wrong with perl configuration.

Ok, I have given up at this point. I like the flatpak concept but would definitely appreciate more information on how to solve such issues. Thank you for all your effort put into improving this product.
