Haven't heard of it but will totally check it out. In order for you to get things going with recording as you have described at home, you'd need the following
A computer
An audio interface, which is what you probably referred to here in this quote. It could be any of these brands but the most common one used by many around the world for home recording is Focusrite 2i2 or 4i4. The former is cheaper and does the job very well. This will allow you to plug both the guitar and vocals and record them both at the same time if you choose/want to.
A good vocal microphone : There are two kinds of mics we'd be looking at here - a conderser mic or a dynamic mic. A condenser would work best for vocals in a good room that is acoustically treated. For home recordings, I suggest you get a nice dynamic microphone. An SM57 or a Sennheiser e835 are my suggestions. Very versatile, can be used not just for vocals but other instruments too. If you have the budget, an SM7B is an incredible purchase. This is my vocal mic at home and I would not trade it for anything.
A good space to record that isn't too noisy
A DAW / Digital Audio Workstation to record, mix, master and produce your music. Reaper or Cakewalk is what I suggest. Both are absolutely free and yet have industry grade tech going into handling sounds. They have loads of stock effects that can help you do everything from scratch and reach the full and final product.
I suggest you look into these to begin with. Once you have some of these things set up and you are getting into setting up the DAW, I'm sure you will have some questions. Pop back in here or create a new topic and I'll be sure to come back and send some resources your way!
