+To run the frontend, you should use Node.js (version 16.x) and npm:
 
 ```
 npm install
 npm run dev
 ```
 
+Then, the frontend will be running on `localhost:5137`.

 <u>Note</u>: You have to change `URL_BACKEND` in file `package.json` to `http://localhost:5000`. Otherwise, the frontend will connect to the backend deployed on `https://costacompas-backend.onrender.com`.
 
 ### Docker Compose
 
-Alternatively, you can use Docker Compose to run the backend and the frontend in two containers. First of all, you may change `URL_BACKEND` in file `package.json` to `http://backend:5000`. Then, you have to run:

 docker compose up -d

+When the containers are running, the frontend will be running inside one of the containers on port `5137`, and the backend on the other container on port `5000`. Those ports are redirected to same ports on the host machine, so you will be able to see the frontend on `localhost:5137`, and the backend on `localhost:5000`.
