I'm very new to this, I'm taking an online course to learn RoR, and I have to install it on my computer before I can go any further in the course. But the course explains how to install it on Mac OSX, but not Windows.

My question is how do you install it the easiest way to understand?

I found a package that include Ruby on Rails, MySQL, Apache, etc. but it was an old version of it, and from what I could tell, they don't have a newer one to download.

Thanks in advance.
