Thanks @aramxc! Could you please rebase main, there is a merge conflict in the README.md

[0xRAG]

@aramxc we require commit signing on all commits, it looks like the first one wasn't signed. Feel free to squash your commits, or remove the first commit.

@0xRAG Sorry for all the noise. I need to stay on top of checking notifications so PRs in active repos dont go stale which caused me a few headaches... Should be good to go!

Could be merged @CarsonRoscoe

Looking at the merge conflict on README.md, this was addressed in another PR that got merged in. Thank you though for the contribution, and apologies for not merging this in time
