Hi,
I have installed the netlifyCMS on my website, and it is all fine.
I created a few collections, and I read the documentation, but I am not sure
would I be able to:
Allow users to see specific collections only?
To see their content only,
could I hide some fields from them?
(Can I add the app metadata to a field or a collection, in other words)
If you want to prevent users to directly modify the default branch you could take the extra step and use branch protection. See About protected branches - GitHub Docs for GitHub.
