 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](https://github.com/tootsuite/mastodon/wiki/Production-guide) for examples, configuration and instructions.
 
+## Deployment on Heroku (experimental)
+
+[![Deploy](https://www.herokucdn.com/deploy/button.svg)](https://heroku.com/deploy)
+
+Mastodon can theoretically run indefinitely on a free [Heroku](https://heroku.com) app. It should be noted this has limited testing and could have unpredictable results.
+
+1. Click the above button.
+2. Fill in the options requested.
+  * You can use a .herokuapp.com domain, which will be simple to set up, or you can use a custom domain. If you want a custom domain and HTTPS, you will need to upgrade to a paid plan (to use Heroku's SSL features), or set up [CloudFlare](https://cloudflare.com) who offer free "Flexible SSL" (note: CloudFlare have some undefined limits on WebSockets. So far, no one has reported hitting concurrent connection limits).
+  * You will want Amazon S3 for file storage. The only exception is for development purposes, where you may not care if files are not saaved. 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.
+
 ## Development with Vagrant
 
 A quick way to get a development environment up and running is with Vagrant. You will need recent versions of [Vagrant](https://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/) installed.
