+Using references
+----------------
+
+Inline references are fully supported (json-pointers) but external can't be resolved by `json-schema-faker`.
+
+In order to achieve that you can use [refaker](https://github.com/gextech/refaker) and then use the resolved schemas:
+
+```javascript
+var schema = {
+  type: 'object',
+  properties: {
+    someValue: {
+      $ref: 'otherSchema'
+    }
+  }
+};
+
+var refs = [
+  {
+    id: 'otherSchema',
+    type: 'string'
+  }
+];
+
+var sample = jsf(schema, refs);
+
+console.log(sample.someValue);
+// output: voluptatem
+```
