I use ** to mark. ** .... ** for bold, * .... * for italic, or *** .... *** for combo, no spaces between words and *.
You can also use # for titles (with a space in between # and title) , [text to display] (link) for hyperlinks and many more.
Markdown uses the same symbols in every platform, you just need to get the hang of it!
