+# MSVC debugger visualizer for YAML::Node
+
+## How to use
+Add yaml-cpp.natvis to your Visual C++ project like any other source file.  It will be included in the debug information, and improve debugger display on YAML::Node and contained types.
+
+## Compatibility and Troubleshooting
+
+This has been tested for MSVC 2017. It is expected to be compatible with VS 2015 and VS 2019. If you have any problems, you can open an issue here: https://github.com/peterchen-cp/yaml-cpp-natvis
