Documentation sites for the LifeFiles project.

rwjf is the main site. design-system is the secondary site.

If hosting these sites elsewhere, the URLs for Brand Book, Design System, Design Principles, Style Guide, and UI Library need to be updated to point to the new hosting location for the LifeFiles Design System site. These can be found on index.html within the rwjf directory. Some other links may also need to be updated during the migration process.
