Help with TP-Link Transition Times

Hey Guys

I’m fairly new to Home Assistant so forgive me for being a noobie.

I’m trying to utilise the transition time on some TP-Link bulbs.

I found this thread: Add Transition Period to TP-Link Smartbulbs

There’s a link to a GitHub page but I wouldn’t know the first thing about how to implement that into HA OS?

Can anyone help me out?
