================================================================
+Alternatively, run `make vcxproj` and then load the generated `git.sln` in
+Visual Studio. The initial build will install the vcpkg system and build the
+dependencies automatically. This will take a while.
+
+Instead of generating the `git.sln` file yourself (which requires a full Git
+for Windows SDK), you may want to consider fetching the `vs/master` branch of
+https://github.com/git-for-windows/git instead (which is updated automatically
+via CI running `make vcxproj`). The `vs/master` branch does not require a Git
+for Windows to build, but you can run the test scripts in a regular Git Bash.
+
+Note that `make vcxproj` will automatically add and commit the generated `.sln`
+and `.vcxproj` files to the repo. This is necessary to allow building a
+fully-testable Git in Visual Studio, where a regular Git Bash can be used to
+run the test scripts (as opposed to a full Git for Windows SDK): a number of
+build targets, such as Git commands implemented as Unix shell scripts (where
+`@@SHELL_PATH@@` and other placeholders are interpolated) require a full-blown
+Git for Windows SDK (which is about 10x the size of a regular Git for Windows
+installation).
+
+If your plan is to open a Pull Request with Git for Windows, it is a good idea
+to drop this commit before submitting.
