* Grammar/Typo, and a rewrite for final paragraph
This paragraph had a few typos and was a little wordy. I've fixed typos, broken it into two paragraphs, and updated the format a bit so we're saying the same thing with less words.
* Update index.md
In the opening David Heinemeier Hansson was incorrectly spelled.
Also, in the same sentence "it's" was incorrectly used and has been corrected to "its".
