+
+To build libevent using Microsoft Visual studio open the "Visual Studio Command prompt" and type:
+
+```
+$ cd <libevent source dir>
+$ cmake -G "Visual Studio 10" ..   # Or whatever generator you want to use cmake --help for a list.
+$ start libevent.sln
+```
+
+Then build the entire solution via the Build menu. 
+
+the "NMake Makefiles" CMake generator can be used to build entirely via the command line.
+
+To get a list of settings available for the project you can type:
+
+```
+$ cmake -LH ..
+```
+
+CMake also provides a GUI that lets you specify the source directory and output (binary) directory
+that the build should be placed in. 
+
+### OpenSSL support
+
+To build Libevent with OpenSSL support you will need to have OpenSSL binaries available when building,
+these can be found here: <http://www.openssl.org/related/binaries.html>
