Hi @Scott,
if you just want German in the frontend, then you can just change the language in the domain of the sales channel from English to German. You will have to change both the language and the snippet-set.
If you want to use both English and German in the frontend, then you will have to add another domain to the sales channel. This can also be a virtual URL (e.g. yourdomain/de). You need two domains in your sales channel for the switcher to work. The sales channel domain settings should look something like this:
- URL _________ Language _______Snippet-set
- yourdomain ___ English_________Base en-GB
- yourdomain/de _ German________ Base de-DE
Kind regards
Patrick
