Type of change

• Bug fix (non-breaking change which fixes an issue)

Checklist before merging

• (Optional) Changes have been linted locally with golangci-lint. (NOTE: We haven't turned on lint checks in the pipeline yet so linting may be hard if it shows a lot of lint errors in places that weren't touched by changes. Thus, linting is optional right now.)

Still need to do copy edits and finalization but this should provide a better structure.

Love all the badges and how much simpler/cleaner this is overall. I do want to fiddle with the wording a bit more in the first section. Feel like we do need a bullet point list of what zarf does / what it's major features are. Also the supported OS link seems to be dead. Would like to get a "build passing" badge too, but think we'd need to have an actual k3s test run on master for that to work. We do it on release right now. Lastly, we desperately need to update the demo to something more up to date, i can try to do that this week.

See #632 for some ideas we can look at adding for the bullet point list.

Will take a stab at updating that text. Where do you see the release action output? I only see where we build and push the release packages not the binary itself.

I like the way the AlexAivazis/survey project does GIFs in their README. It looks like they use gfycat so that playing the GIF doesn't open the link into a new tab and taking you away from the README.

This is a huge improvement over the prior readme, thanks! I made a few changes I'd like you to double-check before we merge @Racer159 or @YrrepNoj

@jeff-mccoy fixed a small grammatical issue but otherwise looks good!
