+If you are sure that you system is ready for the build (see the section 
+"Extra libraries and Utilities" below) and cmake tools then you can build
+the system.
+First, create build directory. you have to run the follow script:
+
+        $ cd coturn
+        $ mkdir build
+
+Then you have to run the configure script:
+
+        $ cmake .. 
+
+It will create a Makefile customized for your system. 
+
+By default, the generated Makefile will install everything to:
+
+	- /usr on Solaris.
+	- /usr/pkg on NetBSD.
+	- /usr/local everywhere else.
+
+The binaries will be copied to the bin subdirectory of the installation 
+destination, config files copied to etc subdirectory. The default SQLite database
+will be created in var/db/turndb. There will be 
+also documents, examples and some other files, in separate directories.
+
+You can change the root configured destination directory by 
+setting CMAKE_INSTALL_PREFIX variable in the 
+configure command line. For example:
+
+        $ cmake .. -DCMAKE_INSTALL_PREFIX=/opt
+
+Build the project:
+
+	$ cmake --build . 
+
+Install all files(runtime programmes and develop library):
+
+        $ cmake --build . --target install
+
+Remove all installed:
+
+        $ cmake --build . --target uninstall
+
+If you want to only install runtime programmes(programmes, configure files,
+script files and database):
+
+        $ cmake --build . --target install-runtime
+
+Remove all installed:
+
+        $ cmake --build . --target uninstall-runtime
