 ## Trio guest mode wrapper for PyGTK
 
-Using the [Trio guest mode](https://trio.readthedocs.io/en/latest/reference-lowlevel.html#using-guest-mode-to-run-trio-on-top-of-other-event-loops) feature, we can run both the Trio and PyGTK event loops alongside each other in a single program. This allows us to make use of the Trio library and the usual `async`/`await` syntax and not have to directly manage thread pools.
-
-This library provides a thin wrapper for initialising the guest mode and exposes a single public API function, `trio_gtk.run` into which you can pass your Trio main function. This function must accept a `nursery` argument which can spawn child tasks for the duration of the host loop.
