 # Storage Special Interest Group
 
-Covers storage and volume plugins.
+SIG Storage is responsible for ensuring that different types of file and block storage (whether ephemeral or persistent, local or remote) are available wherever a container is scheduled (including provisioning/creating, attaching, mounting, unmounting, detaching, and deleting of volumes), storage capacity management (container ephemeral storage usage, volume resizing, etc.), influencing scheduling of containers based on storage (data gravity, availability, etc.), and generic operations on storage (snapshoting, etc.).
+
+The [charter](charter.md) defines the scope and governance of the Storage Special Interest Group.
 
 ## Meetings
 * Regular SIG Meeting: [Thursdays at 9:00 PT (Pacific Time)](https://docs.google.com/document/d/1FQx0BPlkkl1Bn0c9ocVBxYIKojpmrS1CFP5h0DI68AE/edit) (biweekly). [Convert to your timezone](http://www.thetimezoneconverter.com/?t=9:00&tz=PT%20%28Pacific%20Time%29).

+# SIG Storage Charter
+
+This charter adheres to the conventions described in the [Kubernetes Charter README] and uses
+the Roles and Organization Management outlined in [sig-governance].
+
+## Scope
+
+SIG Storage is responsible for ensuring that different types of file and block storage
+(whether ephemeral or persistent, local or remote) are available wherever a container is
+scheduled (including provisioning/creating, attaching, mounting, unmounting, detaching,
+and deleting of volumes), storage capacity management (container ephemeral storage
+usage, volume resizing, etc.), influencing scheduling of containers based on storage
+(data gravity, availability, etc.), and generic operations on storage (snapshoting, etc.).
+
+### In scope
+
+Some notable examples of features owned by SIG Storage:
+
+* Persistent Volume Claims and Persistent Volumes
+* Storage Classes and Dynamic Provisioning
+* Kubernetes volume plugins
+* Container Storage Interface (CSI)
+* Secret Volumes, ConfigMap Volumes, DownwardAPI Volumes, EmptyDir Volumes (co-owned with SIG-Node)
+
+#### Code, Binaries and Services
+
+* Kubernetes internal controllers and APIs responsible for exposing file and block storage to Kubernetes workloads.
+* Kubernetes external sidecar containers and binaries required for exposing file and block storage to Kubernetes workloads.
+* Interfaces required for exposing file and block storage to Kubernetes workloads.
+* Unit, Integration, and End-to-End (E2E) Tests validating and preventing regressions in the above.
+
+#### Cross-cutting and Externally Facing Processes
+
+* Defining interface and requirements for connecting third party storage systems to Kubernetes.
+
+### Out of scope
+
+SIG Storage is not responsible for
+
+* Data path of remote storage (GCE PD, AWS EBS, NFS, etc.)
+  * How bits are transferred.
+  * Where bits are stored.
+* Container writable layer (SIG Node handles that).
+* The majority of storage plugins/drivers (generally owned by storage vendors).
+
+## Roles and Organization Management
+
+SIG Storage adheres to the Roles and Organization Management outlined in [sig-governance]
+and opts-in to updates and modifications to [sig-governance].
+
+### Deviations from [sig-governance]
+
+SIG Storage does not have separate tech leads: SIG Storage chairs serve as tech leads.
+
+### Subproject Creation
+
+SIG Storage delegates subproject approval to Technical Leads. See [Subproject creation - Option 1].
