First off, a few notes:
This was created in response to SEN's melee section. All remarks I make are in reference to them and do not reflect TL. I am the first to say TL is the highest melee authority for info/coverage, and I just thought I'd bring my tutorial over here for anyone who might find it useful.

This tutorial is NSFW in terms of audio. Lots of cursing, pessimism, and my general pissy I-hate-everyone attitude.

This tutorial is extremely basic, isn't perfect, and is generally meant for melee mappers who are just starting out and have no idea what they're doing. You're better off reading the much better guides, however, some people don't have the patience to read walls of text, and prefer video. That's why this was made.

I HIGHLY RECOMMEND WATCHING THIS ON YOUTUBE WITH HQ ON IN FULLSCREEN.

Due to SCMDraft's zoom features and the resolution at which these videos were made, it makes things much clearer.

With that said, here it is.

Edit:
This was recorded in December and I had a bit of a cold at the time hence why I sound so horrible.
