I didn’t see any super simple example around, so here is my attempt. For advanced use, look elsewhere, but here’s the quick and simple way of converting LaTeX to PDF. First, install pdfTeX. It is part of many TeX distributions so you probably already have it. Then, run the following command:
[kota@archdesktop Downloads]$ pdflatex <insert filename here>
A PDF file with the appropriate name should appear in the directory.
