+IGNORES-->
+
+# Ceph RADOS storage driver
+
+An implementation of the `storagedriver.StorageDriver` interface which uses
+[Ceph RADOS Object Storage][rados] for storage backend.
+
+## Parameters
+
+The following parameters must be used to configure the storage driver
+(case-sensitive):
+
+* `poolname`: Name of the Ceph pool
+* `username` *optional*: The user to connect as (i.e. admin, not client.admin)
+* `chunksize` *optional*: Size of the written RADOS objects. Default value is
+4MB (4194304).
+
+This drivers loads the [Ceph client configuration][rados-config] from the
+following regular paths (the first found is used):
+
+* `$CEPH_CONF` (environment variable)
+* `/etc/ceph/ceph.conf`
+* `~/.ceph/config`
+* `ceph.conf` (in the current working directory)
+
+## Developing
+
+To include this driver when building Docker Distribution, use the build tag
+`include_rados`. Please see the [building documentation][building] for details.
