+VSCode
+------
+
+A very simple VSCode client is available in ``clients/vscode/``. Building
+requires nodejs and the :command:`npm` package manager:
+
+.. code-block:: shell-session
+
+   $ npm install
+   $ npm run package
+
+
+Install the created :file:`rpm-spec-language-server-$VERSION.vsix` and launch
+the language server in tcp mode.
