 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/Gargron/mastodon/wiki/Production-guide) for examples, configuration and instructions.
 
+## 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.
+
+Install the latest version for your operating systems, and then run:
+
+    vagrant plugin install vagrant-hostsupdater
+
+This is optional, but will update your 'hosts' file when you start the virtual machine, allowing you to access the site at http://mastodon.dev (instead of http://localhost:3000).
+
+To create and provision a new virtual machine for Mastodon development:
+
+    git clone git@github.com:Gargron/mastodon.git
+    cd mastodon
+    vagrant up
+
+Running `vagrant up` for the first time will run provisioning, which will:
+
+- Download the Ubuntu 14.04 base image, if there isn't already a copy on your machine
+- Create a new VirtualBox virtual machine from that image
+- Run the provisioning script (located inside the Vagrantfile), which installs the system packages, Ruby gems, and JS modules required for Mastodon
+
+Once this has completed, the virtual machine will start a rails process. You can then access your development site at http://mastodon.dev (or at http://localhost:3000 if you haven't installed vagrants-hostupdater). Any changes you make should be reflected on the server instantly.
+
+When you are finished with your session, run `vagrant halt` to stop the VM. Next time, running `vagrant up` should boot the VM, and skip provsioning.
+
+If you no longer need your environment, or if things have gone terribly wrong, running `vagrant destroy` will delete the virtual machine (after which, running `vagrant up` will create a new one, and run provisioning).
