It's good to have the explanation for beginners, but for people that just want to get the software (and kind of know what they're doing) there should be a bigger button in addition to the text link. :)
I'm currently waiting for my Apple and Windows code signing certificates, which will mean I can ditch the while "How to install" pages and just have the binaries install when you click on the big button on the main downloads page. Sadly this seems to be taking a while (I've been waiting on my Windows certificate over 2 weeks now) but I'm hoping I'll get them soon!
I think you should add a bigger "Download" button to your download documentation (i.e. here: http://www.pibakery.org/docs/install-mac.html).
