+
+## Usage Example
+
+This is an example for how use tree-sitter together with the [tree-sitter-c3](https://github.com/c3lang/tree-sitter-c3) grammar.
+
+Add to your project settings:
+```json
+  "dependencies": [ "tree_sitter", "tree_sitter_c3" ],
+```
+
+```c
+import ts;
+import tree_sitter_c3; // tree-sitter-c3 bindings
+
+fn void! main(String[] args) {
+  Language* language = tree_sitter_c3::language();
+  Parser* parser = parser::new_with_language(language)!;
+  defer parser::delete(parser);
+
+  String patterns = `(bitstruct_body (bitstruct_member_declaration ":" @delimiter)+ @member)`;
+
+  Query* query = query::new(language, patterns)!;
+  defer query::delete(query);
+
+  QueryCursor* cursor = ts::query_cursor_new();
+  defer ts::query_cursor_delete(cursor);
+
+  ts::query_cursor_exec(cursor, query, root_node);
+
+  for (QueryMatch match; ts::query_cursor_next_match(cursor, &match);) {
+    QueryCapture! member_capture = match.get_capture("member", query);
+    QueryCapture! delimiter_capture = match.get_capture("delimiter", query);
+    // ...
+  }
+}
+```
