+New Readme Source
+
+This source pulls a single Readme.md from a remote Source repo.
+Typically used for third-party repos which exist already or don't want to
+create a full document hierachy and use `@jpmorganchase/mosaic-source-git-repo`.
+By pulling a single page, we can add metadata to that page via the source's config.
+It's also more performant as we do not need to pull a whole source repo.
