praise: thanks for updating the docs, really appreciated 🙏


With events, you can link your functions with CRON Schedule (time-based) triggers.
With events, you can link your functions with CRON Schedule (time-based) or NATS (message-based) triggers.

To do this you can add an `events` key in your function or container as follows:

nit: I think it's possible to include this directly in the top-level message, since all triggers can be given a name:

events:
 - name: my-nats-event
   nats:
     scw_nats_config:
       ...

However, it's okay like this, the API doesn't define a clear standard for what's a trigger and I don't reckon it's a big deal.

scw_nats_config:
subject: ">"
mnq_nats_account_id: "nats account id"
mnq_project_id: "project id"
mnq_region: "fr-par"
