Steps to follow to work on this template:

1. Clone this repository
2. Set up your firebase project with: firebase init
3. Change to the functions folder cd ./functions/
4. Install all dependencies npm intall
5. Do a local test with the firebase local server npm run serve so you can see that everything is fine.
6. Once you see it running without errors in your local environment, take the project to the server npm run deploy
7. Start the development of your back end using nestJs: npm run start:dev
