How do I actually use mimblewimble

self.litecoin1m ago
I've read several articles about the mimblewimble protocol. But all of those articles lack one thing: explaining how someone actually uses it. Will the function be active with every transaction or d I have to do something to activate it? One article said both parties have to be online. But if I go to my favourite wallet which I normally use to transfer LTC, nothing has changed. Do I need a special wallet software? Can someone pleas explain me how I use the new function in everyday life?
