     wget https://raw.githubusercontent.com/deepforge-dev/deepforge/master/docker/docker-compose.yml
 
+Next, you must decide if you would like authentication to be enabled. For production deployments, this is certainly recommended. However, if you just want to spin up DeepForge to "kick the tires", this is certainly not necessary.
+
+Without User Accounts
+---------------------
+Open the docker-compose file and add the following environment variable to the server:
+
+.. code-block:: bash
+
+    NODE_ENV=default
+
+and delete the volume for the server's keys (used for signing JWTs):
+
+.. code-block:: bash
+
+    - "${TOKEN_KEYS_DIR}:/token_keys"
+
+Next, start the docker containers with
+
+.. code-block:: bash
+
+    docker-compose up
+
+User Authentication Enabled
+---------------------------
+First, generate a public and private key pair
+
+.. code-block:: bash
+
+    mkdir -p deepforge_keys
+    openssl genrsa -out deepforge_keys/private_key
+    openssl rsa -in deepforge_keys/private_key -pubout > deepforge_keys/public_key
+    export TOKEN_KEYS_DIR="$(pwd)/deepforge_keys"
+
 Then start DeepForge using docker-compose:
 
 .. code-block:: bash
 
     docker-compose up
 
-and now DeepForge can be used by opening a browser to `http://localhost:8888 <http://localhost:8888>`_!
+Finally, create the admin user by connecting to the server's docker container. First, get the ID of the container using:
+
+.. code-block:: bash
+
+    docker ps
+
+Then, connect to the running container:
+
+.. code-block:: bash
+
+    docker -it exec <container ID> /bin/bash
+
+and create the admin account
+
+.. code-block:: bash
+
+    ./bin/deepforge users useradd admin <admin email> <password> -c -s
+
+After setting up DeepForge (with or without user accounts), it can be used by opening a browser to `http://localhost:8888 <http://localhost:8888>`_!
