 ## Usage
 
+By default, this gem will use the answer hub default connection credentials (answerhub/answerhub).  You can override defaults by setting content in [a .env file like the example](https://github.com/abelmartin/ahub/blob/master/.env_example) and reference it like this for example:
+
+```bash
+AHUB_ENV_FILE=~/workspace/.ahub_env irb
+```

 ## Development
 
 After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
 
 To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
