+ ## Local debugging with VSCode
+ Steps outlining how to run MCAD locally from your IDE / debugger.
+ - Ensure you are authenticated to your Kubernetes/OpenShift Cluster.
+ - Copy the [launch.json.example](https://github.com/project-codeflare/multi-cluster-app-dispatcher/tree/main/doc/usage/debugger/launch.json.example) file and save it as `launch.json` in the `.vscode` folder in the root of your project.
+ - In the `launch.json` file, update the `args` sections with the path to your kubeconfig.
+ - In VSCode on the activity bar click `Run and Debug` or `CTRL + SHIFT + D` to start a local debugging session of MCAD.
+
+ ### Optional
+ To set the desired log level set `--v`, `<desired_logging_level>` in the args sections of the `launch.json` file.
