Posting games/digrams

I'm probably just overlooking something, but I can't figure out how to get my chess game in one of my posts.  I press the button, then I check off the game circle, and then it asks for one of three things.  PGN, FEN(?), or board editor.  From my game, I got the PGN, and it shows up as an icon on my desktop.

 From here, I'm lost.  What do I do from here?

Find the PGN file on your desktop. Right click on it, select "open with." And open it with 'notepad.'

The text that appears should look something like:

---

[Event "?"]
[Site "?"]
[Date "????.??.??"]
[Round "?"]
[White "?"]
[Black "?"]
[Result "*"]

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6

Now, go back to Chess.com and make a post. When you press the checkard "insert game" button in a post...it'll prompt you for several game types. Click the game circle. Now, it'll ask you for three things: PGN, FEN and board editor. Copy the above text into the "PGN" option. That should do it :)
