+Instructions how to use this in Visual Studio:
+
+Open the worktree as a folder. Visual Studio 2019 and later will detect
+the CMake configuration automatically and set everything up for you,
+ready to build. You can then run the tests in `t/` via a regular Git Bash.
+
+Note: Visual Studio also has the option of opening `CMakeLists.txt`
+directly; Using this option, Visual Studio will not find the source code,
+though, therefore the `File>Open>Folder...` option is preferred.
+
+Instructions to run CMake manually:
+
+    mkdir -p contrib/buildsystems/out
+    cd contrib/buildsystems/out
+    cmake ../ -DCMAKE_BUILD_TYPE=Release
+
+This will build the git binaries in contrib/buildsystems/out
+directory (our top-level .gitignore file knows to ignore contents of
+this directory).
+
+Possible build configurations(-DCMAKE_BUILD_TYPE) with corresponding
+compiler flags
+Debug : -g
+Release: -O3
+RelWithDebInfo : -O2 -g
+MinSizeRel : -Os
+empty(default) :
+
+NOTE: -DCMAKE_BUILD_TYPE is optional. For multi-config generators like Visual Studio
+this option is ignored
+
+This process generates a Makefile(Linux/*BSD/MacOS) , Visual Studio solution(Windows) by default.
+Run `make` to build Git on Linux/*BSD/MacOS.
+Open git.sln on Windows and build Git.
+
+NOTE: By default CMake uses Makefile as the build tool on Linux and Visual Studio in Windows,
+to use another tool say `ninja` add this to the command line when configuring.
