🐰 The maintenance rest, a pause divine,
Our SDK steps back from the line,
Dear users, seek the lexicon way,
With AT Protocol—your trusted stray,
We'll hop back soon, but not today! ✨

@holkexyz @s-adamantine We could also temporarily archive although that might break users of the v0.1 SDK.

I would be in favor of archiving it, BUT only if the people who have used it are aware of it and ok with it.
