# You should know that Docker Compose works with services.
# 1 service = 1 container.
# For example, a service, a server, a client, a database...
# We use the keyword 'services' to start to create services.

    # By default, a Postgres database is running on the 5432 port.

    # Note: You are free to change your computer's port,
    # but take into consideration that it will change the way
    # you are connecting to your database.
