VST instruments and MIDI

Hello,

sorry about asking such a stupid question, but I am completely new to Ardour. I just downloaded it. Okay, I create a session, add a track, and it is audio. No options to make it MIDI. Is MIDI supported? Are VST instruments (or other software synths) supported? If so, how do I add a synth MIDI or automation track?

Thanks!

Ardour2 does not support MIDI (tracks) - Ardour3 (A3) does
