As far as I can say:

1. Edit the page you want to behavior as root page
   1.1. Check Use as Root Page (Tab behaviour)
2. Setup a site configuration (site configuration -> sites -> Add new site configuration for this site)
   2.1 Set a Site identifier (content dont affect the domain; its just used for the folder naming)
   2.2 Set Entry Point to either your domain or to /
   2.3 Variants can be added later and you don't need to ind about as long as you work with just one environment (production; add variants if you also got a local instance with the same code base and a live db dump)
   2.3 Switch to Languages and set your default language (maybe english)
   2.3.1 Choose an available language
   2.3.2 Set an entry point (by default the / should work fine for defualt but you won't get a custom language url snippet generated for /)
   2.3.3 Choose the available Language ID
   2.3.4 Choose the correct Language Key for XLF Files
   2.3.5 Choose the correct Locale (I prefer to set UTF-8 at the end of the locale -> en_US.UTF-8 or de_DE.UTF-8)
   2.3.6 Choose the correct Two Letter ISO Code

Now you should be fine. Just repeat this for every Domain and beginning with step 2.3.1 for every language on the domain

There's an old topic on typo3 wiki about multidomain: https://wiki.typo3.org/Multidomain

I believe the main idea is the same:

1. Create a page. On "Behavior" tab set "Use as root page"
2. Add a domain record to this page
3. Add a template

Also I should notice there's some magic with sorting root pages so I recommend to create all root pages with the same parent
