Hi Abel Berhane thanks for starting this. I agree that the README should be updated but I think some of these changes are better done elsewhere.
> 1) Removed the release notes from upcoming functionality since its been released
I think this is fine, we can take this one forward.
> 2) Added a breakdown of what the Plugin can currently do
I don't want to constantly remember to update the README when updating functionality. The changes are already in the change log and a "basic" upload is catered for in the README. That's as far as I want to go with it (specifically) in the README.
> 3) Added a breakdown of what the Plugin is expecting you to fill out and some helpful hints.
I think this is good but, again, better suited elsewhere. We already have
JENKINS-59377 that looks to cater for this in the appropriate places.
I'll make the same comment on the PR. Thanks.
