+# 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].
