 This will generate an `app.yml` configuration file on your behalf, and then kicks off bootstrap. Bootstrapping takes between **2-8 minutes** to set up your Discourse. If you need to change these settings after bootstrapping, you can run `./discourse-setup` again (it will re-use your previous values from the file) or edit `/containers/app.yml` manually with `nano` and then `./launcher rebuild app`, otherwise your changes will not take effect.
