+          # Usage
+
+          Installing the plugin is simple.
+
+          Ensure that you enabled executor plugins [as described in Argo Workflows' documentation](https://argoproj.github.io/argo-workflows/executor_plugins/).
+
+          Copy the URL to the ConfigMap YAML in this release and apply it with `kubectl`:
+
+          ```
+          kubectl apply -f https://.../wasm-executor-plugin-configmap.yaml
+          ```
+
+          That's all you need to submit a workflow with a Wasm module. Use our example:
+
+          ```
+          kubectl create -f https://raw.githubusercontent.com/Shark/wasm-workflows-plugin/67ae607ec65e1ac93bc1749c5f7a9bde4b673cfd/wasm-modules/examples/ferris-says/workflow.yaml
+          ```
+
+          That's it. :sparkles:
