Since this is your first post, I'm guessing it's a basic question. I do have ReValver (3).. but I've not got the time to install it.. but it should work just like other vst effects.
Assuming you already know how to insert an audio track and record on it. The next step is to insert ReValver as vst effect. You do this by pointing your mouse at the FX box of the audio track, right click and select Audio-FX. Since I've not installed it, I'm not sure if you'll find ReValver under VST2 or VST3 (most likely is VST2) - and it's simple enough to just browse and look for ReValver.
Hope this helps, if not, describe the issue in more detail.
