  *
  * `JsonBuilder` provides an object for generating a JSON tree.
  *
- * You can generate only one tree with one `JsonBuilder` instance.
- *
  * The root of the JSON tree can be either a [struct@Json.Object] or a [struct@Json.Array].
  * Thus the first call must necessarily be either
  * [method@Json.Builder.begin_object] or [method@Json.Builder.begin_array].
  *
  * For convenience to language bindings, most `JsonBuilder` method return the
  * instance, making it easy to chain function calls.
+ *
+ * ## Using `JsonBuilder`
+ *
+ * ```c
+ * g_autoptr(JsonBuilder) builder = json_builder_new ();
+ *
+ * json_builder_begin_object (builder);
+ *
+ * json_builder_set_member_name (builder, "url");
+ * json_builder_add_string_value (builder, "http://www.gnome.org/img/flash/two-thirty.png";);
+ *
+ * json_builder_set_member_name (builder, "size");
+ * json_builder_begin_array (builder);
+ * json_builder_add_int_value (builder, 652);
+ * json_builder_add_int_value (builder, 242);
+ * json_builder_end_array (builder);
+ *
+ * json_builder_end_object (builder);
+ *
+ * g_autoptr(JsonNode) root root = json_builder_get_root (builder);
+ *
+ * g_autoptr(JsonGenerator) gen = json_generator_new ();
+ * json_generator_set_root (gen, root);
+ * g_autofree char *str = json_generator_to_data (gen, NULL);
+ *
+ * // str now contains the following JSON data
+ * // { "url" : "http://www.gnome.org/img/flash/two-thirty.png";, "size" : [ 652, 242 ] }
+ * ```
