# Interactive lessons



Instead of exercises, an interactive course steps through a lesson in the lesson UI. Set
`mode: interactive` and point `lessons` at a JSON file:

```json
{
  "id": "python-setup",
  "title": "Set up Python",
  "steps": [
    { "id": "why", "type": "present", "title": "Why mise", "content": "lessons/why.mdx" },
    {
      "id": "check", "type": "question", "title": "Check",
      "prompt": "Which tool installs Python here?",
      "answers": ["mise"],
      "explanation": "mise installs the tools the course pins in mise.toml."
    }
  ]
}
```

A `present` step shows `content`; a `question` step accepts any of its `answers`, ignoring case,
then shows its `explanation`. Each text field takes inline Markdown or the path of an `.mdx`
file in the course.

Lesson text can use [the lesson content](/authoring/manifest#lesson-content) components.
