wtf is the-old-modernizr.com?

This repository holds the source code for an older version of the Modernizr website. Modernizr itself is a widely used tool that helps websites detect what features a visitor's web browser supports, so developers can adjust how a site behaves accordingly. This particular repo is essentially an archive of the previous website, which also included a tool that let developers build a customized version of Modernizr for their projects. At a technical level, the site was built using Jekyll, which is a simple tool for generating static websites. The README doesn't go into much detail beyond that, other than noting that anyone who wanted to run the site locally would need to have Jekyll installed. There is also a brief link to a separate wiki page with instructions on how the team used to ship new releases back when this version was active. The people who might find this repo useful today are primarily developers or maintainers who want to reference how the older site was structured or how the older custom builder worked. However, the README is clear that this code is no longer current. Anyone looking for the live website's code or wanting to report issues should instead look at the project's newer repository. Ultimately, this is a historical snapshot rather than something a person would actively build on today. It serves as a record of how the project's web presence used to look and function before the team moved on to their current setup.
