-Building on Windows
--------------------
-The easiest way is to use Cmake to create VStudio project. To do that:
-
-* download and install [cmake](http://www.cmake.org/download/) for windows.
-* open the cmake gui and set the source path to `sharedlibpp` and set the
-  build path (for example `sharedlibpp/build`).
-* configure and generate visual studio project.
-* open the project and built it.

 Running example
 ---------------
-The build system by defualt compiles and build the examples.
+The build system by default compiles and build the examples.
 
 * On Linux/Mac
 ```
-    $ cd sharedlibpp/build/examples
-    $ ./math_test mymath.so
-    $ ./math_test_custom mymathcustom.so
+    $ cd shlibpp/build/examples
+    $ ./math_test mymath
+    $ ./math_test_custom mymathcustom

 * On Windows first switch to directory where example is created and then
