How to Write Journal Articles Using LaTeX

I want to write journal articles with a different text editing software because I understand that they are much more able to do more complex and mathematical things better than Word or other common text-editing software. It seems LaTeX will be an ideal candidate. Could you please give me a brief guideline to follow when writing journal articles in LaTeX? This will get me off to a good start, and then I will continue from there to more advance features.
