+In many systems, CMake needs to be installed separately. qlibc requires CMake version 2.8.12 or above.
+Currently, we're focusing on getting the library compiled on those machines using cmake thus it doesn't provide the full configure options as we provide in configure command.

-## Test
+## Examples and Unit Tests.
+
+Analyzing the example code is probably a best starting point to being familiar with qlibc, but please note that the examples were written as simply as possible just to show the sample usages.
+
+As a reminder, example codes and API documents are provided with the package in the "examples" and "doc" directories.
+
+### Run Examples
+
+The examples also can be compiled by running "make" command in the "examples" directory.
+
+```
+$ cd examples
+$ make
+```
+
+If you're using cmake to configure the qlibc package, it will not generate Makefile for codes in examples.
+
+### Run Unit Tests
 
-Sample source and API documents are provided with the package in the "examples" and "doc" directories.
+Currently Unit Tests cover only small portion of codes. This part is in-progress area that we're looking for contributors to enrich this area. 
 
-The examples also can be compiled by typing "make" command in the "examples" directory.
+Unit tests can be compiled and run as following.
 
-Analyzing the example code is probably best starting point, but be aware that the examples were written as simply as possible just to give you straight-forward ideas. So, please refer included API document for more details.
