+### Lazy fetcher
+
+Sometimes you don't want a store, you just want an async function that's gonna handle the errors and leverage the cache (perform cache lookup, save data in there upon successful execution, etc.).
+
+For that case use `fetcherStore.fetch` function. It will always resolve with the same data type as store itself (`error` and `data` only).
+
+Few gotchas:
+
+- it will execute against currently set keys (no way to customize them for the call);
+- it will still leverage deduplication.
