 For `labelRenderer`, you can provide a full path - [see this PR](https://github.com/chibicode/react-json-tree/pull/32).
 
+Their full signatures are:

+- `labelRenderer: function(keyPath, nodeType, expanded, expandable)`
+- `valueRenderer: function(valueAsString, value, ...keyPath)`

 #### More Options
 
-- `shouldExpandNode: function(keyName, data, level)` - determines if node should be expanded (root is expanded by default)
-- `hideRoot: Boolean` - if `true`, the root node is hidden.
-- `sortObjectKeys: Boolean | function(a, b)` - sorts object keys with compare function (optional). Isn't applied to iterable maps like `Immutable.Map`.

+- `postprocessValue: function(value)` - maps `value` to a new `value`
+- `isCustomNode: function(value)` - overrides the default object type detection and renders the value as a single value
+- `collectionLimit: number` - sets the number of nodes that will be rendered in a collection before rendering them in collapsed ranges
+- `keyPath: (string | number)[]` - overrides the initial key path for the root node (defaults to `[root]`)
