Genieacs.env and Quick Start instructions

I’m trying to run GenieACS off master branch, sha1 5c6d850, using the Quick Start instructions and would like to know where I should put genieacs.env?

I installed Genie in /opt/genieacs and just put the file there, but the only thing that matters is that genie can read the file. Then you put your chosen path in your systemd startup files.
