Overview
You can create with pages. Just like other documents you've used, you can fill pages with text and tables, and format them to look pretty, funny, or professional. Also lets you use macros and embed files so that you can have dynamic content in your documents, like videos, Jira issues, roadmaps, and automated reports.
How do pages relate to spaces?
If you think of spaces as separate folders or workspaces that you use to organise your work, pages are the individual items that you use to fill up those folders.
Pages live in a page tree, where they can be nested and organised hierarchically, so you can have pages under pages (under pages). This lets you give your content structure and highlight relationships between pages, such as when you have a parent page about cats, and then child pages under that about different breeds of cats.
