# Quickstart
## Prerequisites
Before installing JupyterHub, you will need:
- a Linux/Unix based system
- [Python](https://www.python.org/downloads/) 3.5 or greater. An understanding
of using [`pip`](https://pip.pypa.io/en/stable/) or
[`conda`](https://conda.io/docs/get-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 npm nodejs-legacy
```
The `nodejs-legacy` package installs the `node` executable and is currently
required for npm to work on Debian/Ubuntu.
- 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
Before running the single-user notebook servers (which may be on the same
system as the Hub or not), you will need:
- [Jupyter Notebook](https://jupyter.readthedocs.io/en/latest/install.html)
version 4 or greater
## 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 notebook # needed if running the notebook servers locally
```
**conda** (one command installs jupyterhub and proxy):
```bash
conda install -c conda-forge jupyterhub # installs jupyterhub and proxy
conda install notebook # needed if running the notebook servers locally
```
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 `https://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.
