 - Create a WebHook in your repo and use the `https` url that `ngrok` printed out after running `ngrok http 4141`. Be sure to append `/events` so your webhook url looks something like `https://efce3bcd.ngrok.io/events`. See [Add GitHub Webhook](https://github.com/hootsuite/atlantis#add-github-webhook).
 - Create a pull request and type `atlantis help`. You should see the request in the `ngrok` and Atlantis logs and you should also see Atlantis comment back.

 - **ALWAYS** use lowercase unless the word requires it
 - **ALWAYS** use `errors.Wrap(err, "additional context...")"` instead of `fmt.Errorf("additional context: %s", err)`

+### Testing
 - place tests under `{package under test}_test` to enforce testing the external interfaces
 - if you need to test internally i.e. access non-exported stuff, call the file `{file under test}_internal_test.go`
 - use `testing_util` for easier-to-read assertions: `import . "github.com/hootsuite/atlantis/testing_util"`
