MultiLang support for theme Learn2

I have managed to setup multilang site but unable to display the language swither.
How to enable language switcher plugin on theme learn2 (rtfm skeleton)?

Did you read the on the LangSwitcher project? You basically just need to include the twig template. It probably makes sense to do this in the sidebar of the theme, or perhaps at the top of the page.

It’s working, I have included the langswitcher in the base.html.twig
