+How to build jemalloc for Windows
+=================================
+
+1. Install Cygwin with at least the following packages:
+   * autoconf
+   * autogen
+   * gawk
+   * grep
+   * sed
+
+2. Install Visual Studio 2015 with Visual C++
+
+3. Add Cygwin\bin to the PATH environment variable
+
+4. Open "VS2015 x86 Native Tools Command Prompt"
+   (note: x86/x64 doesn't matter at this point)
+
+5. Generate header files:
+   sh -c "CC=cl ./autogen.sh"
+
+6. Now the project can be opened and built in Visual Studio:
+   msvc\jemalloc_vc2015.sln
+
