Hi SI Team

I have been reading the article here:

https://stackideas.com/blog/simple-steps-to-identify-and-configure-translations-for-joomla

And I am wondering how does this actually work when implemented succesfully?

(In my case I am looking at the idea of setting this up for English and German)

In my limited experienced of multilingual sites, there are flags with the languages and you swtich manually!

Does this work like this or does it work some how else?

I hope this is clear what I am asking?

thanks

Paul
