How do I edit a document that I uploaded and make the changes stay?

[Refugio]

I uploaded a document and I wanted to add more sections without having to upload the document over and over. I have tried adding child pages but they don't show up in the document table of contents. The child pages show up on the side bar but not in the table of contents in the document page. I need help. Thank you.

Welcome to the Atlassian Community!

I think, when you say "document", you mean "attachment".  Attachments are files that are added to pages, they are not Confluence pages you can directly edit.

You have to download, edit and re-attach the new version.

Thank you for the response.
