     Take a blocking function and create an async one that receives the same
-    positional and keyword arguments, and that when called, calls the original function
-    in a worker thread using `anyio.to_thread.run_sync()`. Internally,
-    `asyncer.asyncify()` uses the same `anyio.to_thread.run_sync()`, but it supports
-    keyword arguments additional to positional arguments and it adds better support for
-    autocompletion and inline errors for the arguments of the function called and the
-    return value.
-
-    If the `cancellable` option is enabled and the task waiting for its completion is
-    cancelled, the thread will still run its course but its return value (or any raised
-    exception) will be ignored.
+    positional and keyword arguments. For python version 3.9 and above, it uses
+    asyncio.to_thread to run the function in a separate thread. For python version
+    3.8, it uses locally defined copy of the asyncio.to_thread function which was
+    introduced in python 3.9.
 
-    Use it like this:
+    Usage:
 
-    ```Python
-    def do_work(arg1, arg2, kwarg1="", kwarg2="") -> str:
-        # Do work
-        return "Some result"
+    ```python
+    def blocking_func(arg1, arg2, kwarg1=None):
+        # blocking code
+        return result
 
 
-    result = await to_thread.asyncify(do_work)("spam", "ham", kwarg1="a", kwarg2="b")
-    print(result)
+    result = asyncify(blocking_function)(arg1, arg2, kwarg1=value1)
     ```
 
     ## Arguments
 
     `function`: a blocking regular callable (e.g. a function)
-    `cancellable`: `True` to allow cancellation of the operation
-    `limiter`: capacity limiter to use to limit the total amount of threads running
-        (if omitted, the default limiter is used)
