I want to work on this. @pingou can you please guide me :)

So what do you want to know :)

Can I use sphnix-git for changelogs and once we have put changelogs in rst file should i remove it from spec file

The change log is already in the spec file, so why do you want to use sphinx-git?

Then how can we generate/move logs in rst file?

My simple idea was to create a new rst file and copy/paste there the content from the spec file and then reformat said content to look pretty.

Would this not work? Do you have something else in mind?

Does someone every-time building the project updates the changelog tag entries?

Any objections in following what is done on bodhi release_notes ???
