+# 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

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your patches! Before we can take them, we have to jump a
+couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement
+(CLA).
+
+*   If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an
+    [individual CLA](https://developers.google.com/open-source/cla/individual).
+*   If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a
+    [corporate CLA](https://developers.google.com/open-source/cla/corporate).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Are you a Googler?
+
+If you are a Googler, please make an attempt to submit an internal change rather
+than a GitHub Pull Request. If you are not able to submit an internal change a
+PR is acceptable as an alternative.
+
+## Contributing A Patch
+
+1.  Submit an issue describing your proposed change to the
+    [issue tracker](https://github.com/google/googletest).
+2.  Please don't mix more than one logical change per submittal, because it
+    makes the history hard to follow. If you want to make a change that doesn't
+    have a corresponding issue in the issue tracker, please create one.
+3.  Also, coordinate with team members that are listed on the issue in question.
+    This ensures that work isn't being duplicated and communicating your plan
+    early also generally leads to better patches.
+4.  If your proposed change is accepted, and you haven't already done so, sign a
+    Contributor License Agreement (see details above).
+5.  Fork the desired repo, develop and test your code changes.
+6.  Ensure that your code adheres to the existing style in the sample to which
+    you are contributing.
+7.  Ensure that your code has an appropriate set of unit tests which all pass.
+8.  Submit a pull request.
+
+## The Google Test and Google Mock Communities
+
+The Google Test community exists primarily through the
+[discussion group](http://groups.google.com/group/googletestframework) and the
+GitHub repository. Likewise, the Google Mock community exists primarily through
+their own [discussion group](http://groups.google.com/group/googlemock). You are
+definitely encouraged to contribute to the discussion and you can also help us
+to keep the effectiveness of the group high by following and promoting the
+guidelines listed here.
+
+### Please Be Friendly
+
+Showing courtesy and respect to others is a vital part of the Google culture,
+and we strongly encourage everyone participating in Google Test development to
+join us in accepting nothing less. Of course, being courteous is not the same as
+failing to constructively disagree with each other, but it does mean that we
+should be respectful of each other when enumerating the 42 technical reasons
+that a particular proposal may not be the best choice. There's never a reason to
+be antagonistic or dismissive toward anyone who is sincerely trying to
+contribute to a discussion.
+
+Sure, C++ testing is serious business and all that, but it's also a lot of fun.
+Let's keep it that way. Let's strive to be one of the friendliest communities in
+all of open source.
+
+As always, discuss Google Test in the official GoogleTest discussion group. You
+don't have to actually submit code in order to sign up. Your participation
+itself is a valuable contribution.
+
+## Style
+
+To keep the source consistent, readable, diffable and easy to merge, we use a
+fairly rigid coding style, as defined by the
+[google-styleguide](https://github.com/google/styleguide) project. All patches
+will be expected to conform to the style outlined
+[here](https://google.github.io/styleguide/cppguide.html). Use
+[.clang-format](https://github.com/google/googletest/blob/master/.clang-format)
+to check your formatting
+
+## Requirements for Contributors
+
+If you plan to contribute a patch, you need to build Google Test, Google Mock,
+and their own tests from a git checkout, which has further requirements:
+
+*   [Python](https://www.python.org/) v2.3 or newer (for running some of the
+    tests and re-generating certain source files from templates)
+*   [CMake](https://cmake.org/) v2.6.4 or newer
+
+## Developing Google Test and Google Mock
+
+This section discusses how to make your own changes to the Google Test project.
+
+### Testing Google Test and Google Mock Themselves
+
+To make sure your changes work as intended and don't break existing
+functionality, you'll want to compile and run Google Test and GoogleMock's own
+tests. For that you can use CMake:
+
+    mkdir mybuild
+    cd mybuild
+    cmake -Dgtest_build_tests=ON -Dgmock_build_tests=ON ${GTEST_REPO_DIR}
+
+To choose between building only Google Test or Google Mock, you may modify your
+cmake command to be one of each
+
+    cmake -Dgtest_build_tests=ON ${GTEST_DIR} # sets up Google Test tests
+    cmake -Dgmock_build_tests=ON ${GMOCK_DIR} # sets up Google Mock tests
+
+Make sure you have Python installed, as some of Google Test's tests are written
+in Python. If the cmake command complains about not being able to find Python
+(`Could NOT find PythonInterp (missing: PYTHON_EXECUTABLE)`), try telling it
+explicitly where your Python executable can be found:
+
+    cmake -DPYTHON_EXECUTABLE=path/to/python ...
+
+Next, you can build Google Test and / or Google Mock and all desired tests. On
+\*nix, this is usually done by
+
+    make
+
+To run the tests, do
+
+    make test
+
+All tests should pass.
+
+### Regenerating Source Files
+
+Some of Google Test's source files are generated from templates (not in the C++
+sense) using a script. For example, the file
+include/gtest/internal/gtest-type-util.h.pump is used to generate
+gtest-type-util.h in the same directory.
+
+You don't need to worry about regenerating the source files unless you need to
+modify them. You would then modify the corresponding `.pump` files and run the
+'[pump.py](googletest/scripts/pump.py)' generator script. See the
+[Pump Manual](googletest/docs/pump_manual.md).

+
+## Welcome to **Google Test**, Google's C++ test framework!
+
+This repository is a merger of the formerly separate GoogleTest and GoogleMock
+projects. These were so closely related that it makes sense to maintain and
+release them together.
+
+Please subscribe to the mailing list at googletestframework@googlegroups.com for
+questions, discussions, and development.
+
+### Getting started:
+
+The information for **Google Test** is available in the
+[Google Test Primer](googletest/docs/primer.md) documentation.
+
+**Google Mock** is an extension to Google Test for writing and using C++ mock
+classes. See the separate [Google Mock documentation](googlemock/README.md).
+
+More detailed documentation for googletest is in its interior
+[googletest/README.md](googletest/README.md) file.
+
+## Features
+
+*   An [xUnit](https://en.wikipedia.org/wiki/XUnit) test framework.
+*   Test discovery.
+*   A rich set of assertions.
+*   User-defined assertions.
+*   Death tests.
+*   Fatal and non-fatal failures.
+*   Value-parameterized tests.
+*   Type-parameterized tests.
+*   Various options for running the tests.
+*   XML test report generation.
+
+## Platforms
+
+Google test has been used on a variety of platforms:
+
+*   Linux
+*   Mac OS X
+*   Windows
+*   Cygwin
+*   MinGW
+*   Windows Mobile
+*   Symbian
+*   PlatformIO
+
+## Who Is Using Google Test?
+
+In addition to many internal projects at Google, Google Test is also used by the
+following notable projects:
+
+*   The [Chromium projects](http://www.chromium.org/) (behind the Chrome browser
+    and Chrome OS).
+*   The [LLVM](http://llvm.org/) compiler.
+*   [Protocol Buffers](https://github.com/google/protobuf), Google's data
+    interchange format.
+*   The [OpenCV](http://opencv.org/) computer vision library.
+*   [tiny-dnn](https://github.com/tiny-dnn/tiny-dnn): header only,
+    dependency-free deep learning framework in C++11.
+
+## Related Open Source Projects
+
+[GTest Runner](https://github.com/nholthaus/gtest-runner) is a Qt5 based
+automated test-runner and Graphical User Interface with powerful features for
+Windows and Linux platforms.
+
+[Google Test UI](https://github.com/ospector/gtest-gbar) is test runner that
+runs your test binary, allows you to track its progress via a progress bar, and
+displays a list of test failures. Clicking on one shows failure text. Google
+Test UI is written in C#.
+
+[GTest TAP Listener](https://github.com/kinow/gtest-tap-listener) is an event
+listener for Google Test that implements the
+[TAP protocol](https://en.wikipedia.org/wiki/Test_Anything_Protocol) for test
+result output. If your test runner understands TAP, you may find it useful.
+
+[gtest-parallel](https://github.com/google/gtest-parallel) is a test runner that
+runs tests from your binary in parallel to provide significant speed-up.
+
+[GoogleTest Adapter](https://marketplace.visualstudio.com/items?itemName=DavidSchuldenfrei.gtest-adapter)
+is a VS Code extension allowing to view Google Tests in a tree view, and
+run/debug your tests.
+
+## Requirements
+
+Google Test is designed to have fairly minimal requirements to build and use
+with your projects, but there are some. If you notice any problems on your
+platform, please notify
+[googletestframework@googlegroups.com](https://groups.google.com/forum/#!forum/googletestframework).
+Patches for fixing them are welcome!
+
+### Build Requirements
+
+These are the base requirements to build and use Google Test from a source
+package:
+
+*   [Bazel](https://bazel.build/) or [CMake](https://cmake.org/). NOTE: Bazel is
+    the build system that googletest is using internally and tests against.
+    CMake is community-supported.
+
+*   a C++11-standard-compliant compiler
+
+## Contributing change
