* `exampleMode` — Initial state of the code example tab
* `usageMode` — Initial state of the props and methods tab

```
{
  name: 'UI Components',	       name: 'UI Components',
  content: 'docs/ui.md',	       content: 'docs/ui.md',
  components: 'lib/components/ui/*.js',
+  sectionDepth: 2,
+  exampleMode: 'expand', // 'hide' | 'collapse' | 'expand'
