How do i create multi-lingual content in the Admin plugin?

I found that adding the default.{lang}.md file to be the easiest way so far, once my folder and default .md document are created (using add page in the admin panel). However how would i go about creating each page for the different languages in the admin panel?

I had a look in the "Learn" section of the site and this is not covered, that i can find. Could someone point me in the right direction please?

Worked it out! At the top there is a dropdown icon on the save button. In there you can select your language and save the file. This created the correct files in the folder too.
