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 Scalingo dashboard.
