+`yaml-cpp` uses [CMake](http://www.cmake.org) to support cross-platform building. Install [CMake](http://www.cmake.org) _(Resources -> Download)_ before proceeding. The basic steps to build are:
 
-1. Download and install [CMake](http://www.cmake.org) (Resources -> Download).
+**Note:** If you don't use the provided installer for your platform, make sure that you add `CMake`'s bin folder to your path.
 
-**Note:** If you don't use the provided installer for your platform, make sure that you add CMake's bin folder to your path.
+#### 1. Navigate into the source directory, create build folder and run `CMake`:
 
-2. Navigate into the source directory, and type:
+```sh
-
-```
 mkdir build
 cd build
+cmake [-G generator] [-YAML_BUILD_SHARED_LIBS=on|OFF] ..
 ```
 
-3. Run CMake. The basic syntax is:
+  * The `generator` option is the build system you'd like to use. Run `cmake` without arguments to see a full list of available generators.
+    * On Windows, you might use "Visual Studio 12 2013" (VS 2013 32-bits), or "Visual Studio 14 2015 Win64" (VS 2015 64-bits).
+    * On OS X, you might use "Xcode".
+    * On a UNIX-like system, omit the option (for a Makefile).
 
-```
+  * `yaml-cpp` builds a static library by default, you may want to build a shared library by specifying `-YAML_BUILD_SHARED_LIBS=ON`.
-cmake [-G generator] [-DYAML_BUILD_SHARED_LIBS=ON|OFF] ..
-```
-
-  * The `generator` is whatever type of build system you'd like to use. To see a full list of generators on your platform, just run `cmake` (with no arguments). For example:
-    * On Windows, you might use "Visual Studio 12 2013" to generate a Visual Studio 2013 solution or "Visual Studio 14 2015 Win64" to generate a 64-bit Visual Studio 2015 solution.
-    * On OS X, you might use "Xcode" to generate an Xcode project
-    * On a UNIX-y system, simply omit the option to generate a makefile
-
-  * yaml-cpp defaults to building a static library, but you may build a shared library by specifying `-DYAML_BUILD_SHARED_LIBS=ON`.
 
   * For more options on customizing the build, see the [CMakeLists.txt](https://github.com/jbeder/yaml-cpp/blob/master/CMakeLists.txt) file.
 
-4. Build it!
+#### 2. Build it!
+  * The command you'll need to run depends on the generator you chose earlier.
 
-5. To clean up, just remove the `build` directory.
+**Note:** To clean up, just remove the `build` directory.
