removing one of the environment setup options

@beechnut I like your .env documentation better than the template.env style. 
.env is already in the gitignore, so there is already a barrier to unsuspecting people committing their keys.
I think 10 or 15 minutes is really excessive for animal shelters. There's just not that much turnover in pets.
I'm going to talk to someone I know who volunteers at the MSPCA and try to get an idea about what the rate is.
