So I'm learning apex via http://www.sfdc99.com/ 

Now he simple states, get a free dev org, i did that and then go through steps xyz to connect mavensmate...problem is mavensmate is no longer supported. 

So i installed all the packages need for visual studio code, but for the love of all things holy i cannot figure out how to connect it. Also whenever i log into my free dev org i'm not sure if im in sandbox or in the dev org, there's literally nothing different (other than one has less content).

I also have a corporate account, obviously i cant use the firms enterprise edition...
