Thread:Project:Support desk/Enable extension:flow/reply (3)

The page in fact does tell you how to enable the extension, that is by simply installing it. However, it does not say much about what the extension does. That might be caused by the fact that this is an early alpha version and maybe the developers do not yet know, what exactly the extension should do in the future.

Also take care of the notes on the page, one of them being: "Installation? Just don't." I think that sums it up nicely.
