+## Typescript Refrence

+You can maually find the definition files in the `types` folder. A quick summary, is rougly as follows:
+
+```ts
+import * as TreeModel from "tree-model";
+
+interface TestModel {
+    name: string;
+}
+const tree = new TreeModel({});
+const root = tree.parse<TestModel>({ name: 'a', children: [{ name: 'b' }, { name: 'c' }] });
+```
+It is also possible to type the input object (to parse) itself, instead of providing the generic type to `.parse`:
+
+```ts
+const data : TreeModel.Model<TestModel> = { name: 'a', children: [{ name: 'b' }, { name: 'c' }] };
+const root = tree.parse(data);
+```
