+- If you do not currently have the Mollie note on your WooCommerce Admin home screen, you can add a test note with the correct name as follows:
+    1. install the WooCommerce Admin Test Helper plugin [here](https://github.com/woocommerce/woocommerce-admin-test-helper)
+    2. Go to the Admin notes tab
+    3. Add an admin note with the name `wc-admin-effortless-payments-by-mollie`
+    4. Go to the WCA home screen and verify that your test note is present
+- The note is removed on a new version install, so either install an old version of WCA and upgrade to the current one, or trigger the install process manually:
+    1. install the WCA test helper
+    2. go to the Tools tab
+    3. click the `Trigger WCA install` button
