Nostr is append only, if an event is published to someone else's relay, you can't delete it.

oh yes, i get that about nostr. my question relates to updating the website.

if i have 5 pages, which i publish to nostr using this tool, and then i make a small change to one of the pages, do i then need to create and publish the entire project again?

it relies on the hash of the contents ex. if you uploaded your website for the first time it get fully uploaded, but incase you have changed some contents lets stay 1 page out of 5, it compares the hash of the assets, and just upload the changed assets, same as the retrieval, unchanged cached contents didn't get retrieved from the relays
