For a quick and easy introduction a step-by-step tutorial would be fruitful. Possible parts could be:

• Installation
• Configuration
• Execution in a simulated environment
• Data transfer
• Example integration of dtn7 into application software

I wonder if setting a demo environment up in Kubernetes would be interesting? At least a small test setup with a deployment you could scale up.
