Thanks! For the merge conflicts: you don't actually need to update the README. I have a github action that will make sure it's up-to-date.

[chrisgrieser]

ah, I see. should I just reset the file?

edit: oh, I see, the bot was already active. Yeah, I just resolved the merge conflict.

[chrisgrieser]

check failed due to wrong indentation in a file. Pushed a fix

Looks like another merge conflict >.<

You can just ignore the README changes entirely and only commit the new files. The bot will follow up with a commit like ee679d1 and add the proper entries.

[chrisgrieser]

yeah, the merge conflict came from the fact that you merged a PR with new linters in the meantime :(

anyway, I just resolved the conflict, which should do it

[stevearc]

Thanks for the PR!
