+# WG Sidecar
+
+This charter adheres to the conventions described in the [Kubernetes Charter README]
+and uses the Roles and Organization Management outlined in [sig-governance].
+
+[sig-governance]: https://github.com/kubernetes/community/blob/master/committee-steering/governance/sig-governance.md
+[Kubernetes Charter README]: https://github.com/kubernetes/community/blob/master/committee-steering/governance/README.md
+
+## Scope
+
+The sidecar WG was created to work thru the requirements, design, implementation,
+and future plans of natively supporting sidecar pattern in Kubernetes.
+
+### In Scope
+
+- Create a KEP for 1.27
+- Provide supporting materials for easier KEP approval
+- Approve the KEP for 1.27
+- Discuss and coordinate implementation in 1.28
+- Also the working group will reach out to various areas experts to finalize the implementation details.
+
+
+## Stakeholders
+
+Stakeholders in this working group span multiple SIGs with the SIG Node as a primary SIG.
+
+- SIG Node
+  Primary SIG as the most changes are in kubelet.
+- SIG Scheduling
+  APIs and changes related to Pods scheduling.
+- SIG Architecture
+  High-level input on requirements and API.
+- SIG Apps
+  Input on requirements for batch-like workload and other usage of sidecars.
+
+## Deliverables
+
+The ultimate deliverable is a built-in support of Sidecar containers in Kubernetes.
+
+## Roles and Organization Management
+
+This sig follows adheres to the Roles and Organization Management outlined in
+[sig-governance] and opts-in to updates and modifications to [sig-governance].
+
+[sig-governance]: https://github.com/kubernetes/community/blob/master/committee-steering/governance/sig-governance.md
+
+## Timelines and Disbanding
+
+We hope to get Sidecar KEP merged in 1.28 and finalize any additional requirements
+and future plans in year 2023. Group will be discontinued once the feature GA-d
+and there is not major follow up feature requiring extensive collaboration.
