+According with Wikipedia, GNU Emacs is a free software text editor. It was created by GNU Project founder Richard Stallman. In common with other varieties of Emacs, GNU Emacs is extensible using a Turing complete programming language. GNU Emacs has been called "the most powerful text editor available today". GNU Emacs is sometimes abbreviated as GNUMACS, especially to differentiate it from other EMACS variants. The tag line for GNU Emacs is "the extensible self-documenting text editor".
+
+We are going to use GNU Emacs and configure it with Vanilla flavoured style theme.

+
+## Controlling your emacs configuration
+
+In order to control your changes into the emacs configuration file, it is recommended to make a symbolic link to this repository. Thus, let us first clone this repository and create a symbolic link by using:
+
+```
+$ git clone http://gmarxcc.com:8088/mcie-rs101/emacs-configuration.git
+$ cd emacs-configuration
+$ ln -s /home/user-name/folder/of/emacs-configuration/.emacs /home/user/.emacs 
+```
+
+by doing this, we are going to link both files and register any modification.
