+
+Documentation regarding the Ultimate end-to-end tests.
+
+## Overview
+
+The ultimate e2e test scenario covers native-to-erc type of bridge.
+It runs the e2e tests on components deployed using the deployment playbooks.
+
+
+## Usage
+
+### 1. Prepare the infrastructure
+
+Run the Parity nodes, deploy the bridge contracts, deploy Oracle using the deployment playbook.
+
+```bash
+./up.sh deploy native-to-erc
+```
+
+### 2. Run the E2E tests
+
+```
+docker-compose run e2e yarn workspace oracle-e2e run native-to-erc
+```
