+## How does Serverless Container healthcheck work ?
+
+A Serverless Container is set to `ready` once the specified port is correctly bound to the container, and will start receiving traffic. If your application needs to perform some tasks before receiving traffic (e.g. connect to a database), it's important to run them before binding to the port (starting the webserver).
+For now, the `HEALTHCHECK` Docker directive has no impact on container readiness. In the future, the healthcheck will be customizable for your applications.
