 `jotai-derive` provides a primitive for building asynchronous data graphs
 that act on values as soon as they are available (either awaiting for them, or acting on them synchronously).
 
+Use of this utility can cause the [Release of Zalgo](https://blog.izs.me/2013/08/designing-apis-for-asynchrony/) if used improperly.

+asynchronous case and the synchronous case (both `await` and `soon(...)` will help).
