Documenting design decisions is a honorable piece of work.
“(…) a style guide is a living document of code, which details all the various elements and coded modules of your site or application. Beyond its use in consolidating the front-end code, it also documents the visual language, such as header styles and color palettes, used to create the site. This way, it’s a one-stop place for the entire team—from product owners and producers to designers and developers—to reference when discussing site changes and iterations. Several companies have even put their guides online; Starbucks is the most well known of the bunch, but others exist.”
