include a last-updated line
You mention on the generator that the site is updated regularly, but we don't know when you wrote that. The build guide has a last updated line, and that's good, but newbs could feel extra-confident in the build they generate if they know you looked at this algorithm recently.
Great site by the way, thanks so much for making it!
Some parts are continually automatically updated whereas others are adjusted manually but these should also be regularly updated within a week making it impractical and not entirely truthful to add a ‘last updated’ line
