Confluence: How do I create separate sections in my instance?
How do I create separate sections in my environment?
How do I segment my Confluence instance?
To have separate sections for your different documentation, you can create several spaces in your Confluence instance.
You'll be able to find back these spaces in your space directory, in your dashboard or in your space menu. You can check this blog post or this documentation to learn how to organize your spaces.
As there is no limit on the number of spaces you can create, you will be able to create new ones according to your needs.
