+What you are reading now is not comments, I swear!
+
+After many years of programming I decided to think different about
+programming and solve the problems in a better way.
+
+We are writing commands or code and the Ring language is reading
+it to understand us! Sure, What you are seeing now is
+just ***part of the code - Not the Complete Program***
+You have to write little things before and after this
+part to be able to run it!
+
+It is the natural part of our code where we can write in English,
+Arabic or any Natural Language Then we will tell the computer
+through the Ring language what must happens! in a way that we can scale
+for large frameworks and programs.
+
+Just imagine what will happens to the world of programming once
+we create many powerful frameworks using the Ring language that
+uses this way (Natural Programming).
+
+For example When we say Hello to the Machine, It can reply! and when we
+say count from 1 to 5 it will understand us, Also if
+we said count from 5 to 1 it will
+understand us too! You can see the Output window!
+
+This Goal is not new, but the Ring language comes
+with an innovative solution to this problem.
