Monitor a file for changes and send an alert

This flow monitors a file for changes of its content. If changed, an alert is sent out and you receive it as push, SMS or voice call on SIGNL4. User cases: Log-file monitoring Monitoring of production data Integration with third-party systems via file interface Etc. Sample file "alert-data.json": { "Body": "Alert in building A2.", "Done": false, "eventId": "25180887437222013724ee5617b-2731-4d38-8e16-e4148b8fb8a0" } Body: The alert text to be sent. Done: If false this is a new alert. If true this indicated the alert has been closed. eventId: Last SIGNL4 event ID written by SIGNL4. This flow can be easily adapted for database monitoring as well.

Help me set up the n8n workflow "Monitor a file for changes and send an alert" (https://n8n.io/workflows/967). It uses: SIGNL4. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
