There's also a bunch of other markup you can do. 

\~~this~~ Looks like ~~this~~

\*this* Looks like *this*

\*\*this** Looks like **this**

\^this Looks like ^this

\#this Looks like

 #this

And now the word "this" doesn't sound like a real word. You're welcome.

^Thanks, *didn’t* know **these** earlier
