+## SpinKube Project Compatibility Matrix
+
+All versions are backwards compatible, so using a new Spin Operator on an older Spin containerd shim should not break the execution of an application; however, not all new features added to the `SpinApp` custom resource may be available to the shim. For example, OTEL support for monitoring Spin applications was added to the shim in `v0.15.0` and the ability to pipe OpenTelemetry parameters to the shim from a `SpinApp` was added in the Spin Operator `v0.3.0`. This means that people using the `v0.3.0` operator with a shim version less than `v0.15.0` may expect OTEL to be configured for their Spin app.
+
+## Spin Operator and Shim Feature Map
+
+At time, features are added to the Spin Runtime that are added to the shim and can be enabled through the Spin Operator.

+| Feature | SpinApp field | Shim Version | Spin Operator Version | `spin kube` plugin version |

+| OTEL Traces | `otel` | v0.15.0 | v0.3.0 | NA |
+| Selective Deployment | `components` | v0.17.0 | v0.4.0 | v0.4.0 |
