+Code hangs when I stop, restart, add/remove_handler
+---------------------------------------------------
+
+You tried to ``.stop()``, ``.restart()``, ``.add_handler()`` or ``.remove_handler()`` *inside* a running handler, but
+that can't be done because the way Pyrogram deals with handlers would make it hang.
+
+When calling one of the methods above inside an event handler, Pyrogram needs to wait for all running handlers to finish
+in order to safely continue. In other words, since your handler is blocking the execution by waiting for the called
+method to finish and since Pyrogram needs to wait for your handler to finish, you are left with a deadlock.
+
+The solution to this problem is to pass ``block=False`` to such methods so that they return immediately and the actual
+code called asynchronously.
