 This command will start a Tor node and open ports 9001 and 9030:
 
 ``` console
 docker run -d -p 9001:9001 -p 9030:9030 --name tor svengo/tor

 Data is stored in an anonymous volume that is mounted on ``/data`` (see docker inspect for more information). You can use a host volume to store the data in a specific directory on the host. The directory could exist, the permissions are handled by the container.

+### Basic configuration
 
 Use environment variables for basic configuration. The contents of the environment variables are used to build `/etc/tor/torrc-defaults`. For more advanced configuration you can edit the `/data/torrc` configuration file directly.
 
 ``` console
 docker run -d -p 9001:9001 -p 9030:9030 --name tor -v /data/tor:/data -e "NICKNAME=MyDockerTorNode" -e "CONTACTINFO=foo@example.com" svengo/tor``

-### Environment Variables
+#### Environment Variables
 
 svengo/tor uses several environment variables to generate the ``torrc-defaults``-file, the variables are set to reasonable defaults (see below). You can edit ``/data/torrc`` to your needs after the first run.

 `EXITPOLICY=policy,policy,…`
 
 Set an exit policy for this server. Each policy is of the form "accept[6]|reject[6] ADDR[/MASK][:PORT]". If /MASK is omitted then this policy just applies to the host given. Instead of giving a host or network you can also use "*" to denote the universe (0.0.0.0/0 and ::/128), or *4 to denote all IPv4 addresses, and *6 to denote all IPv6 addresses. PORT can be a single port number, an interval of ports "FROM_PORT-TO_PORT", or "*". If PORT is omitted, that means "*".

 The IPv4 address of this server, or a fully qualified domain name of this server that resolves to an IPv4 address.  You can leave this unset, and Tor will try to guess your IPv4 address.  This IPv4 address is the one used to tell clients and other servers where to find your Tor server; it doesn't affect the address that your server binds to.  It also seems to work with an IPv6 address.
