+* *Keep*: Keep is the Arvados storage system for managing and storing large
+collections of files. Keep combines content addressing and a
+distributed storage architecture resulting in both high reliability
+and high throughput. Every file stored in Keep can be accurately
+verified every time it is retrieved. Keep supports the creation of
+collections as a flexible way to define data sets without having to
+re-organize or needlessly copy data. Keep works on a wide range of
+underlying filesystems and object stores.
