You can write your own articles on the platform and publish them.
You can add an article by going to the admin panel (Click on your profile picture > Administration panel). Then press 'Blog posts' > 'New post'. The writing can begin!
Note: don't forget to add the right segment to make the blog post appear on a certain page. You can find the segments under 'Post metadata' when you edit your blog post.
You can select only one language for a post. If you want to have the post in another language, please create another post and set it to that language.
