Only have one "About" page

[tmtmtmtm]

There are effective two "About" pages at the minute. The link on the front page goes to what is essentially the main Documentation page, but which acts as a general (though brief) introduction. There is also /about (although it's not as obvious that you can click on the section header to get there), but that text is much older, and needs a lot more work.

The documentation entry point now doesn't have much in the way of "about" details and the about page has been updated with new copy.
