 ## Components
 Each loaded component provides its name, type and version and also information about supported features in the form of component capabilities. 
-These features are available for the [state store]({{< ref supported-state-stores.md >}}), [pub/sub]({{< ref supported-pubsub.md >}}) and [binding]({{< ref supported-bindings.md >}}) component types. The table below shows the component type and the list of capabilities for a given version. This list might grow in future and only represents the capabilities of the loaded components.

+## Component format
+To setup in-memory state store, create a component of type `state.in-memory`. See [this guide]({{< ref "howto-get-save-state.md#step-1-setup-a-state-store" >}}) on how to create and apply a state store configuration.
+
+```yaml

+kind: Component
+metadata:
+  name: <NAME>
+  namespace: <NAMESPACE>
+spec:
+  type: state.in-memory
+  version: v1
+  metadata: []
+```
+
+> Note: While in-memory does not require any specific metadata for the component to work, `spec.metadata` is a required field.
