[TechBeme]

Goal

Create a contributor-friendly tutorial showing how to add one model end to end.

Suggested content

• Choose a provider and official model ID.
• Define image or video capabilities.
• Map provider-specific inputs and outputs.
• Explain reference media slots and adaptive controls.
• Validate model discovery, submission, polling and result rendering.
• Document how to test without committing credentials or generated user media.

The guide should use a real existing integration as its example and link directly to the relevant source files.
