+[cquery](https://github.com/cquery-project/cquery) provides extremely fast,
+robust, and reliable C++ integration into vscode with a ton of features, like
+code lens, references, code completion, semantic highlighting, and much more.
+
+You currently need to install and build the main cquery server (eventually this
+will be downloaded for you from prebuilts). See the [Getting
+Started](https://github.com/cquery-project/cquery/wiki/Getting-started) wiki
+entry.
+
+This extension is still in preview. Please see additional documentation at the
+main cquery
+[wiki](https://github.com/cquery-project/cquery/wiki/Visual-Studio-Code).
