+Visual Studio 2017 - library and zint.exe
+-----------------------------------------
+
+To build the zint library DLL and the command line tool "zint.exe" with PNG support:
+
+Install git (https://git-scm.com/downloads)
+Install cmake (https://cmake.org/download/)
+
+Open a "Developer Command Prompt for VS 2017" (should be available under the
+"Visual Studio 2017" tab in the Start menu).
+
+Make sure git and cmake are in your PATH, e.g. (your paths may differ)
+
+  set PATH="C:\Program Files\Git\cmd";%PATH%
+  set PATH="C:\Program Files\CMake\bin";%PATH%
+
+Download zint, zlib and libpng by going to the directory you want to clone them
+into:
+
+  cd <project-directory>
+
+and cloning each:
+
+  git clone https://git.code.sf.net/p/zint/code zint
+  git clone https://git.code.sf.net/p/libpng/code lpng
+  git clone https://github.com/madler/zlib.git zlib
+
+First build zlib:
+
+  cd zlib
+
+  nmake -f win32\Makefile.msc LOC="-DASMV -DASMINF=" OBJA="inffas32.obj match686.obj"
+
+  cd ..
+
+and then lpng:
+
+  cd lpng
+
+  cmake -G"Visual Studio 15 2017"^
+        -DCMAKE_BUILD_TYPE=Release^
+        -DPNG_BUILD_ZLIB=ON^
+        -DZLIB_INCLUDE_DIRS=..\zlib^
+        -DPNG_STATIC=ON^
+        -DPNG_SHARED=OFF^
+        -H.^
+        -Bbuild
+
+  cmake --build build --config Release
+
+  cd ..
+
+If you now open "<project-directory>\zint\win32\zint.sln" with Visual Studio
+2017, you should be able to build both the Release and Debug configurations.

+Visual Studio 2015
+------------------
+
+The solution and project files for Visual Studio 2015 have been moved to the
+sub-directory vs2015 and are no longer maintained. However by copying the steps
+above and adapting the settings from the Visual Studio 2017 project files (and
+adding any sources missing), they should be pretty serviceable.
