+# Configuration Basics
+
+The section contains basic information about configuring settings for a JupyterHub
+deployment. The [configuration reference](./configuration-guide.html)
+provides additional detail.
+
+This section will help you learn how to:
+
+- generate a default configuration file, `jupyterhub_config.py`
+- start with a specific configuration file
+- configure JupyterHub using command line options
+- find information and examples for some common deployments
+
+## Generate a default config file
+
+On startup, JupyterHub will look by default for a configuration file,
+`jupyterhub_config.py`, in the current working directory.
+
+To generate a default config file, `jupyterhub_config.py`:
+
+```bash
+jupyterhub --generate-config
+```
+
+This default `jupyterhub_config.py` file contains comments and guidance for all
+configuration variables and their default values. We recommend storing
+configuration files in the standard UNIX filesystem location, i.e.
+`/etc/jupyterhub`.
+
+## Start with a specific config file
+
+You can load a specific config file and start JupyterHub using:
+
+```bash
+jupyterhub -f /path/to/jupyterhub_config.py
+```
+
+If you have stored your configuration file in the recommended UNIX filesystem
+location, `/etc/jupyterhub`, the following command will start JupyterHub using
+the configuration file:
+
+```bash
+jupyterhub -f /etc/jupyterhub/jupyterhub_config.py
+```
+
+The IPython documentation provides additional information on the
+[config system](http://ipython.readthedocs.io/en/stable/development/config.html)
+that Jupyter uses.
+
+## Configure using command line options
+
+To display all command line options that are available for configuration:
+
+```bash
+    jupyterhub --help-all
+```
+
+Configuration using the command line options is done when launching JupyterHub.
+For example, to start JupyterHub on ``10.0.1.2:443`` with https, you
+would enter:
+
+```bash
+    jupyterhub --ip 10.0.1.2 --port 443 --ssl-key my_ssl.key --ssl-cert my_ssl.cert
+```    
+
+All configurable options may technically be set on the command-line,
+though some are inconvenient to type. To set a particular configuration
+parameter, `c.Class.trait`, you would use the command line option,
+`--Class.trait`, when starting JupyterHub. For example, to configure the
+`c.Spawner.notebook_dir` trait from the command-line, use the
+`--Spawner.notebook_dir` option:
+
+```bash
+jupyterhub --Spawner.notebook_dir='~/assignments'
+```
+
+## Configure for various deployment environments
+
+The default authentication and process spawning mechanisms can be replaced, and
+specific [authenticators](./authenticators-users-basics.html) and
+[spawners](./spawners-basics.html) can be set in the configuration file.
+This enables JupyterHub to be used with a variety of authentication methods or
+process control and deployment environments. [Some examples](./config-examples.html),
+meant as illustration, are:
+
+- Using GitHub OAuth instead of PAM with [OAuthenticator](https://github.com/jupyterhub/oauthenticator)
+- Spawning single-user servers with Docker, using the [DockerSpawner](https://github.com/jupyterhub/dockerspawner)
