Install Primer 9.5.0

Primer has undergone a lot of changes in the past 18 months. We've been consolidating and updating the CSS to make more resuable and flexible styles, we turned Primer CSS into a monorepo and improved our build process, and we've been building a new documentation website that we'll make public in fall, 2017. In the meantime, you can still view the old documentation website, or you can find up-to-date documentation for styles within the README.md or docs folder of each Primer module.

Packages

Primer CSS includes 23 packages that are grouped into 3 core meta-packages for easy install. Each package and meta-package is independently versioned and distributed via npm, so it's easy to include all or part of Primer within your own project.
