+[QML][] grammar for the [tree-sitter][] parsing library.

+References
+----------
+
+* https://code.qt.io/cgit/qt/qtdeclarative.git/tree/src/qml/parser/qqmljs.g
+
+Pitfalls
+--------
+
+Since grouped binding notation is syntactically ambiguous, it is parsed as
+an object definition.
+
+```qml
+// (ui_object_definition type_name: (identifier "Button") ...)
+Button {
+    // (ui_object_definition type_name: (identifier "icon") ...)
+    icon { source: "foo.png"; color: "transparent" }
+}
+```
+
+Building
+--------
+
+Use the `master` branch, which contains all generated files.
+
+```
+$ git checkout master
+$ npm install
+$ cargo build --release
+```
+
+Hacking
+-------
+
+Use the `dev` branch, but you'll first need to run `npm install` in the
+`master` branch.
+
+```
+$ git checkout master
+$ npm install
+$ git checkout dev
+```
+
+Generate code and run tests:
+```
+$ make generate tests
+```
+
+Make sure example QML files can be parsed:
+```
+$ make fetch-examples parse-examples
+```
