### How to install $\LaTeX$

So, you want to produce professional quality typesetting of mathematical formulae? Look no further. You will need a distribution of LaTeX. A tremendous resource in addition to (or perhaps even in place of) this article is the LaTeX Project. Windows: MiKTeX or ProTeXt Since ProTeXt is MiKTeX based I will only cover the installation of ProTeXt. However ProTeXt is probably easier to install and anyway, it is the recommended distribution for Windows from the LaTeX Project.
