+copy `default_settings.json` file from `test/e2e/templates/` directory to `.vscode/` directory and modify it as per your needs.
+
+You can now use Run and Debug menu to launch
+- Debug E2E Test
+  - This runs the test suite in debug mode. You can add breakpoints to step through the end to end test.
+  - Prerequisites:
+    - You have installed OADP Operator. To install current commit run `make deploy-olm`
+- Launch main.go
+  - This runs the operator on your machine in debug mode. You can add breakpoints and step through the code.
+  - You will not see OADP in Installed Operators but it will be watching for DPA resources in the namespace as if it was installed.
+  - Prerequisites:
+    - Run `make install apply-velerosa-role` to install CRDs and create service accounts, a task normally handled by OLM but not in this case.
