+# Quickstart
+
+## Prerequisites
+
+Before installing JupyterHub, you will need:
+
+- a Linux/Unix-based system
+- [Python](https://www.python.org/downloads/) 3.6 or greater. An understanding
+  of using [`pip`](https://pip.pypa.io) or
+  [`conda`](https://docs.conda.io/projects/conda/en/latest/user-guide/getting-started.html) for
+  installing Python packages is helpful.
+- [nodejs/npm](https://www.npmjs.com/). [Install nodejs/npm](https://docs.npmjs.com/getting-started/installing-node),
+  using your operating system's package manager.
+
+  - If you are using **`conda`**, the nodejs and npm dependencies will be installed for
+    you by conda.
+
+  - If you are using **`pip`**, install a recent version of
+    [nodejs/npm](https://docs.npmjs.com/getting-started/installing-node).
+    For example, install it on Linux (Debian/Ubuntu) using:
+
+    ```
+    sudo apt-get install nodejs npm
+    ```
+
+    [nodesource][] is a great resource to get more recent versions of the nodejs runtime,
+    if your system package manager only has an old version of Node.js (e.g. 10 or older).
+
+- A [pluggable authentication module (PAM)](https://en.wikipedia.org/wiki/Pluggable_authentication_module)
+  to use the [default Authenticator](./getting-started/authenticators-users-basics.md).
+  PAM is often available by default on most distributions, if this is not the case it can be installed by
+  using the operating system's package manager.
+- TLS certificate and key for HTTPS communication
+- Domain name
+
+[nodesource]: https://github.com/nodesource/distributions#table-of-contents
+
+Before running the single-user notebook servers (which may be on the same
+system as the Hub or not), you will need:
+
+- [JupyterLab][] version 3 or greater,
+  or [Jupyter Notebook][]
+  4 or greater.
+
+[jupyterlab]: https://jupyterlab.readthedocs.io
+[jupyter notebook]: https://jupyter.readthedocs.io/en/latest/install.html
+
+## Installation
+
+JupyterHub can be installed with `pip` (and the proxy with `npm`) or `conda`:
+
+**pip, npm:**
+
+```bash
+python3 -m pip install jupyterhub
+npm install -g configurable-http-proxy
+python3 -m pip install jupyterlab notebook  # needed if running the notebook servers in the same environment
+```
+
+**conda** (one command installs jupyterhub and proxy):
+
+```bash
+conda install -c conda-forge jupyterhub  # installs jupyterhub and proxy
+conda install jupyterlab notebook  # needed if running the notebook servers in the same environment
+```
+
+Test your installation. If installed, these commands should return the packages'
+help contents:
+
+```bash
+jupyterhub -h
+configurable-http-proxy -h
+```
+
+## Start the Hub server
+
+To start the Hub server, run the command:
+
+```bash
+jupyterhub
+```
+
+Visit `http://localhost:8000` in your browser, and sign in with your Unix
+credentials.
+
+To **allow multiple users to sign in** to the Hub server, you must start
+`jupyterhub` as a _privileged user_, such as root:
+
+```bash
+sudo jupyterhub
+```
+
+The [wiki](https://github.com/jupyterhub/jupyterhub/wiki/Using-sudo-to-run-JupyterHub-without-root-privileges)
+describes how to run the server as a _less privileged user_. This requires
+additional configuration of the system.
