I’m trying to get a multisite installation of discourse working with a different domain for each site and I’m getting a bit confused by the instructions [Multisite configuration with Docker](https://meta.discourse.org/t/multisite-configuration-with-docker/14084)

I’ve seen all the warnings about this being an advanced topic and fully confess that I’d never used docker before installing Discourse. On the other hand, I still need to get it working if we’re going to use Discourse regardless of my lack of docker expertise 🙂

I’ve got a single site installation up and running. The instructions talk about copying a pasting a new hooks section into the app.yml file (I think?) and talk about amending the host\_names node in multisite.yml. I’m confused about where the multisite.yml file comes from? Do I need this in addition to the app.yml file? Also once I’ve got these files do I need to do a rebuild or something or will it all work automatically?
