 ## Overview
 
 ### ICP Node
+
 The ICP node provides a local canister execution environment that enables you to deploy canisters to test your dapps during development. This simulates having a node of the blockchain running.
 
 ### Backend Canisters
+
 These are the set of canisters (or smart contracts) which hold the bounty service logic and manage funds and users.
 
 ### GitHub App
+
 This GitHub app runs using an `.env` file containing credentials, and it serves to route webhook calls into canister calls, depending on the users' interactions on the GitHub platform.
 It also exposes a REST API for the opeartor.
 This is useful, for example, to verify the github app can reach the canisters by calling the /bounty/healthcheck endpoint as follows:
+
 ```sh
 curl http://localhost:3000/bounty/healthcheck
 ```

 ## Running End-to-End (E2E) Tests
+
 > Note: Each component must be run in its own terminal session, and all commands should be executed from the root directory of the project. This ensures that the processes do not interfere with each other and that the project’s file paths are correctly referenced.
 
 To kick off the E2E tests, you need to set up an environment with the following components:
 
 1. **ICP Node**: Start the local Internet Computer (IC) replica node.
-    ```sh
-    dfx start
-    ```
+
+   ```sh
+   dfx start --clean
+   ```
 
 2. **Backend Canisters**: Deploy the backend canisters to the replica and generates the candid interface.
-    ```sh
-    make install
-    ```
+
+   ```sh
+   make install
+   npm run generate
+   ```
 
 3. **GitHub App**: Start the GitHub application.
-    ```sh
-    cd offchain/github && npm start
-    ```
+   ```sh
+   cd offchain/github && npm start
+   ```
 
 Finally, you can run the E2E tests by executing:
+
 ```sh
 cd offchain/github && npm test
 ```
