This is a guide to install Minion Pro and Myriad Pro for the use with MikTeX's pdflatex. Overall this guide aimed at entry-level users.
If you want to work through the guide, simply click on Download ZIP above and then, after unzipping, open the file named mpro-installation-guide-miktex.pdf. That's it. :)
If you have questions, please do not hesitate to ask here at latex-community.org or the good folks at TeX.SX, they are a highly compentent bunch and you will certainly learn good amount of other things about LaTeX. :)
There is also Sebastian Schubert's version of Minion Pro and Myriad Pro: https://github.com/sebschub/FontPro.
They are newer and certainly easy to install on a UNIX-like system. I recommend to check it out and give it a try!
