-## Quick Installation
-The quick way to install The Littlest JupyterHub (tljh) is:
-
-```bash
-curl https://raw.githubusercontent.com/yuvipanda/the-littlest-jupyterhub/master/installer/install.bash | sudo bash -
-```
-
-This takes 2-5 minutes to run. When completed, you can access your new JupyterHub
-at the public IP of your server!
-
-You should probably add yourself as an [admin user](admin.md)
-after installation.
-
-## Slightly less quick installation
-
-If you can read `bash` and are nervous about the previous installation method,
-you can inspect the installer script before running it.
-
-1. Download the installer script
-
-   ```bash
-   curl https://raw.githubusercontent.com/yuvipanda/the-littlest-jupyterhub/master/installer/install.bash  -o install.bash
-   ```
-
-2. Read the install script source using your favorite text editor
-
-3. Run the installer script
-
-   ```bash
-   sudo install.bash
-   ```
-
- This should have the exact same effects as the quick installer method.

+Tutorial: JupyterHub in under 10 minutes
+========================================
+
+Goal
+----
+
+By the end of this tutorial, you should have a JupyterHub with some admin
+users and user environment with packages you want installed. This is 80% of what
+most users need, so is a great place to start
+
+Pre-requisites
+--------------
+
+#. A fresh Ubuntu 18.04 server
+#. Full root access
+#. Some familiarity with the command line
+#. Public IP for your server, so you can access your hub from the internet
+
+Step 1: Install the Littlest JupyterHub (TLJH)
+----------------------------------------------
+
+``ssh`` into the server, and install TLJH.
+
+.. code-block:: bash
+
+   curl https://raw.githubusercontent.com/yuvipanda/the-littlest-jupyterhub/master/installer/install.bash | sudo bash -
+
+This takes about 1-3 minutes to finish. When completed, you can visit the
+public IP of your server to use your JupyterHub! You can log in with any username
+and password combination.
+
+Step 2: Add admin user
+----------------------
+
+You should add yourself as an admin user, so you can administer the JupyterHub
+from inside JupyterHub itself. Making someone admin gives them ``root`` access to
+the server, allowing them to make whatever changes they want.
+
+TLJH is configured with a ``config.yaml`` files, written in `YAML <https://yaml.org>`_ syntax.
+We will modify ``config.yaml`` to list admin users, and then restart JupyterHub to
+let the changes take effect.
+
+1. Open the ``config.yaml`` file for editing.
+
+   .. code-block:: bash
+
+      sudo nano /opt/tljh/config.yaml
+
+2. Add usernames that should have admin access.
+
+   .. code-block:: yaml
+
+      users:
+        admin:
+          - user1
+          - user2
+
+   Be careful around the syntax - indentation matters, and you should be using
+   spaces and not tabs.
+
+   When you are done, save the file and exit. In ``nano``, you can do this with
+   ``Ctrl+X`` key.
+
+3. Restart jupyterhub so the changes can take effect.
+
+   .. code-block:: bash
+
+      sudo systemctl restart jupyterhub
+
+   This should not disrupt any active users on your JupyterHub.
+
+   If the user you made admin is already logged in, you might have to restart your
+   notebook server via the Control Panel page accessed from top right of your web
+   interface for your new superpowers to take effect.
+
+4. Open a terminal in your notebook server (New -> Terminal) & check if sudo works.
+
+   .. code-block:: console
+
+     $ sudo -E id
+       uid=0(root) gid=0(root) groups=0(root)
+
+Congratulations, you are now an admin user in JupyterHub! Most administrative
+actions can now be performed from inside the Terminal in Jupyter Notebooks,
+without requiring SSH usage.
+
+Step 3: Install conda / pip packages for all users
+--------------------------------------------------
+
+The **User Environment** is a conda environment that is shared by all users
+in the JupyterHub. Libraries installed in this environment are immediately
+available to all users. Admin users can install packages in this environment
+with ``sudo -E``.
+
+1. As an admin user, open a terminal in your notebook server
+2. Install ``numpy`` from `conda-forge <https://conda-forge.org/>`_.
+
+   .. code-block:: bash
+
+      sudo -E conda install -c conda-forge numpy
+
+   The ``sudo -E`` is very important!
+
+3. Install ``there`` with ``pip``
+
+   .. code-block:: bash
+
+      sudo -E pip install there
+
+The packages ``numpy`` and ``there`` are now available to all users in JupyterHub!
