+How dow I get the result of a task if I have the ID that points there?
+----------------------------------------------------------------------
+
+**Answer**: Use ``Task.AsyncResult``::
+
+    >>> result = MyTask.AsyncResult(task_id)
+    >>> result.get()
+
+This will give you a :class:`celery.result.BaseAsyncResult` instance
+using the tasks current result backend.
+
+If you need to specify a custom result backend you should use
+:class:`celery.result.BaseAsyncResult` directly::
+
+    >>> from celery.result import BaseAsyncResult
+    >>> result = BaseAsyncResult(task_id, backend=...)
+    >>> result.get()
+
