 On Windows, you'll need to install Python to run `configure.py`, and

+running `vcvarsall` in a normal command prompt).
+
+For other combinations such as gcc/clang you will need the compiler
+(gcc/cl) in your PATH and you will have to set the appropriate
+platform configuration script.
+
+See below if you want to use mingw or some other compiler instead of
+Visual Studio.
+
+##### Using Visual Studio
+Assuming that you now have Python installed, then the steps for building under
+Windows using Visual Studio are:
+
+Clone and checkout the latest release (or whatever branch you want). You
+can do this in either a command prompt or by opening a git bash prompt:
+
+```
+    $ git clone git://github.com/ninja-build/ninja.git && cd ninja
+    $ git checkout release
+```
+
+Then:
+
+1. Open a Windows command prompt in the folder where you checked out ninja.
+2. Select the Microsoft build environment by running
+`vcvarsall.bat` with the appropriate environment.
+3. Build ninja and test it.
+
+The steps for a Visual Studio 2015 64-bit build are outlined here:
+
+```
+    > "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x64
+    > python configure.py --bootstrap
+    > ninja --help
+```
+Copy the ninja executable to another location, if desired, e.g. C:\local\Ninja.
+
+Finally add the path where ninja.exe is to the PATH variable.
