Edit Wiki file "1.-Building-Fritzing.md"

I’d like to suggest the modification (diff) in the wiki page as in link bellow. The text is clearer and updated. I am sorry for posting this wiki pull request here but I couldn’t find the way to do that in github. Could you please tell me how to do wiki pull requests?

It seems that is not supported in GitHub. See git - How can I make a pull request for a wiki page on GitHub? - Stack Overflow for a workaround.
Or you can upload the patch to an issue in github.
