 description: |
-  Contains swift-object, swift-container and swift-account servers.
+ OpenStack Object Storage (code-named Swift) is open source software for
+ creating redundant, scalable object storage using clusters of standardized
+ servers to store petabytes of accessible data. It is not a file system or
+ real-time data storage system, but rather a long-term storage system for a
+ more permanent type of static data that can be retrieved, leveraged, and
+ then updated if necessary. Primary examples of data that best fit this
+ type of storage model are virtual machine images, photo storage, email
+ storage and backup archiving. Having no central "brain" or master point of
+ control provides greater scalability, redundancy and permanence.
+ .
+ This charm deploys the Swift storage service, supporting HTTP based access
+ via Swift proxy services.
