+## Interact with Aave in Mainnet via console
+
+You can interact with Aave at Mainnet network using the Hardhat console, in the scenario where the frontend is down or you want to interact directly. You can check the deployed addresses at https://docs.aave.com/developers/deployed-contracts.
+
+Run the Hardhat console pointing to the Mainnet network:
 
-# A new Bash terminal is prompted, connected to the container
-npm run test:main:check-list
+```
+docker-compose run contracts-env npx hardhat --network main console
+```
+
+At the Hardhat console, you can interact with the protocol:
+
+```
+// Load the HRE into helpers to access signers
+run("set-DRE")
+
+// Import getters to instance any Aave contract
+const contractGetters = require('./helpers/contracts-getters');
+
+// Load the first signer
+const signer = await contractGetters.getFirstSigner();
