     - We do not look for PushEvents because those are usually used for personal projects, not actual open source contributions.
     - Starfish allows you to filter events based on the specific action taken. For example, you might want to count when a pull request is opened, but not when it is closed. To do that, the list of important events can include basic types (like "PullRequestEvent") or a specific action of a type (like "PullRequestEvent.closed").
         You can list multiple actions for the same event type. Visit [GitHub event types](https://docs.github.com/en/free-pro-team@latest/developers/webhooks-and-events/github-event-types#event-object-common-properties) for more information.
