 ## Advanced usage (with the nginx and docker-gen containers)
 
-**nginx-proxy** can also be run as two separate containers using the [jwilder/**docker-gen**](https://github.com/jwilder/docker-gen) image and the official [**nginx**](https://hub.docker.com/_/nginx/) image. You may want to do this to prevent having the docker socket bound to a publicly exposed container service (ie avoid mounting the docker socket in the nginx exposed container).

 **NOTE**: The first time this container is launched in a three container setup, it will generates a new 2048 bits Diffie-Hellman parameters file. This process can take up to several minutes to complete on lower end hosts, and certificates creation won't start before that (be patient).

 The methods for each container are sorted by order of precedence, meaning that if you use both the label and the volumes_from method, the ID of the **nginx**/**nginx-proxy** container that will be used will be the one found using the label. **There is no point in using more than one method at a time for either the nginx/nginx-proxy or docker-gen container beside potentially confusing yourself**.
 
-The advantage the `label` methods have over the `environment variable` (and `volumes_from`) methods is enabling the use of the **acme-companion** in environments where containers names are dynamic, like in Swarm Mode or in Docker Cloud. Howhever if you intend to do so, as upstream **docker-gen** lacks the ability to identify containers from labels, you'll need both to either use the two containers setup or to replace jwilder/docker-gen with a fork that has this ability like [herlderco/docker-gen](https://github.com/helderco/docker-gen). Be advised that for now, this works to a very limited extent [(everything has to be on the same node)](https://github.com/nginx-proxy/acme-companion/pull/231#issuecomment-330624331).
