* `DISCOURSE_HOSTNAME` should be `discourse.example.com` or something similar.

**Email is CRITICAL for account creation and notifications in Discourse.** If you do not properly configure email before bootstrapping YOU WILL HAVE A BROKEN SITE!
* `DISCOURSE_DEVELOPER_EMAILS` should be a list of admin account email addresses separated by commas.
* `DISCOURSE_SMTP_ADDRESS`
* `DISCOURSE_SMTP_USER_NAME`
* `DISCOURSE_SMTP_PASSWORD`
