 Docker is great for quickly trying out software, but it has its drawbacks too. If you prefer to run Mastodon without using Docker, refer to the [production guide](docs/Running-Mastodon/Production-guide.md) for examples, configuration and instructions.

+
+1. Click the above button.
+2. Fill in the options requested.
+  * You can use a .scalingo.io domain, which will be simple to set up, or you can use a custom domain.
+  * You will want Amazon S3 for file storage. The only exception is for development purposes, where you may not care if files are not saved. Follow a guide online for creating a free Amazon S3 bucket and Access Key, then enter the details.
+  * If you want your Mastodon to be able to send emails, configure SMTP settings here (or later). Consider using [Mailgun](https://mailgun.com) or similar, who offer free plans that should suit your interests.
+3. Deploy! The app should be set up, with a working web interface and database. You can change settings and manage versions from the Heroku dashboard.
+
+You may need to use the `scalingo` CLI application to run `USERNAME=yourUsername rails mastodon:make_admin` to make yourself an admin.
