[Tex/LaTex] Installing amsthm.sty under MiKTeX


On the LaTeX wikibooks I saw that there is an easy way to make theorems: http://en.wikibooks.org/wiki/LaTeX/Theorems

The problem is that \usepackage{amsthm} doesn't work – asmthm.sty is not found. And scanning the MiKTeX Package Manager, surely, I didn't find it either.
How is it possible to obtain the amsthm.sty and thereafter installing it. So far I've been lucky enough to have the Package Manager doing all the fuss automatically for me.

The file amsthm.sty is part of MiKTeX's amscls package. Using the MiKTeX Package Manager, you should install amscls. You will probably want to install the amsmath package as well, for any mathematical typesetting.

In general, you can find out which MiKTeX package any file is in, by typing the full file name (such as in this case amsthm.sty) into the box at the top of the package manager labelled File name: and then clicking the Filter button.
