 ## React Use Async Fn
 
-React hook for managing the state of an async function
+React hook for managing the state of async function and abortable async functions
+
+### Features
+- Execute and track not only API requests but any async functions.
+- Abort async functions. Can be used to abort fetch API calls.
+- Simple API to `await` async function to get its result while the hook manages the state.
+- Callbacks for notifying success and error

+#### useAbortableAsync(props)
+
+This function manages the state of an async function which can be aborted.  
+
+The `fn` prop requires the last argument to be of `AbortableLifecycle` to use this hook.
+
+**props**
+

+
+#### STATUSES
+
+Enum of statuses
+
+`INITIAL`: The status before triggering  
+`WORKING`: The status after triggering but before completion  
+`DONE`: The status when completed successfully
