Looks awesome! Thanks for the PR 🙂 Could you just move the new entry at the end of the api-docs group instead of the end of the file?

[pawamoy]

I'm now wondering if api-docs is the right category 🤔 I'll merge anyway, feel free to send another PR if you want to change the category 🙂

[Kl0ven]

Thanks :)
Yes, api-docs is pushing it, would it be worth creating a architecture-doc ?

I'd prefer not adding new categories with a single item in them. I also agree that it doesn't really fit in other categories. Maybe "integration with other tools"? As in, it integrates with ADR in general. I'm fine with keeping it in API docs for now 🤷 As you want!
