HelpDocs supports permission groups so you can restrict access to articles in your knowledge base. This means you can host both internal and external articles within the same knowledge base, and can easily manage access at an article-by-article level.
How it works
To get started with permissioning, you first need to create a permission group and add users to it. Once you have your permissions groups, you can assign groups to articles in the article editor, in just a few clicks.
