Follow that guide if you want to be a generic minecraft youtuber, but there's a ton of those, even a tutorial on it! You just have to clever and creative, having an intro/outro isn't going to get you noticed, good and interesting content will.
Don't be one of those "HEY GUYS ITS {name}, AND TODAY WE WILL BE...", then spit out a lame joke and laugh, there's plenty of dem.
