Edit the config.json configuration file with the desired filters for events that should invoke the service and src/index.js with your service logic. The service function signature is:

export const handler = async (newEvents, eventStore, state) => {
    let currentState = state;

    return currentState;
}

Where newEvents is an array of Nostr events that triggered the function, eventStore is an ordered list of events that triggered the function in the past and state is a cached current state of the service returned by the last time it was invoked.
