Use of jekyll-i18n_tags plugin

Hello, I built my jekyll project with jekyll-i18n_tags plugin. (

As the documentation says it is enough to add the language in the front matter like

lang: fr for french


lang: en for english

and use the liquid tags

{% t Hello, world! %}

but the language is so hardcoded. I don’t see the usability to have multiple language this way. To be convenient, we should be able to change the language dynamically by clicking in on a flag for example. How can we change dynamically the language ?

Hello, I finally set up the translation of my jekyll pages thanks to this tutorial : It is very well explained. Thanks for reading my post. The question is solved
