+Build Steps for Windows
+-------------------------
+
+Follow https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2#building_pecl_extensions
+
+- Add igbinary module to pecl directory if support desired
+- Download/Compile libmemcached & add to deps folders (includes & lib). Lib should be named memcache.lib
+	- Important for 32bit: libmemcached must be built with _USE_32BIT_TIME_T defined (confirmed on PHP 7.2, VC15)
+	- https://github.com/yshurik/libmemcached-win/tree/1.0.18 is confirmed working
+	- To use the dll on the releases page you'd likely need to change the header files to use __time64_t instead of time_t
+- Enable all options desired: --enable-memcached=shared --enable-memcached-session --enable-memcached-json
+	- for igbinary, add --enable-memcached-igbinary --enable-igbinary=shared
+- Run nmake
