 The automatic redirection to HTTPS is turned off by default in development. If you need to test this behavior, put `FORCE_TO_HTTPS=true` in your `.env` file.
 
+## Development Installation (using Docker)
+
+Using Docker, you can have a complete, consistent development environment
+without having to manually install dependencies such as Node, Mongo, etc. It
+also helps isolate these dependencies and their data from other projects that
+you may have on the same computer that use different/conflicting versions, etc.
+
+1. Install Docker for your operating system
+   * Mac: https://www.docker.com/docker-mac
+   * Windows: https://www.docker.com/docker-windows
+2. Clone this repostory and cd into it
+3. `$ docker-compose build`
+4. `$ docker-compose run --rm server yarn run fetch-examples`
+
+Now, anytime you wish to start the server with its dependencies, you can run:
+
+5. `$ docker-compose up`
+6. Navigate to [http://localhost:8000](http://localhost:8000) in your browser
+
+To open a terminal/shell in the running Docker server (i.e. after `docker-compose up` has been run):
+
+7. `$ docker-compose exec server bash -l`
+
+If you don't have the full server environment running, you can launch a one-off container instance (and have it automatically deleted after you're done using it):
+
+8. `$ docker-compose run server --rm bash -l`
+
 ## Production Installation
 1. Clone this repostory and `cd` into it
 2. `$ git submodule init`
