-====== The Linux Shell ======
+====== Logging in with X Windows ======
 The standard user interface for personal computers is a GUI (Graphical User Interface). However for linux it is a command-line interpreter called shell.
 It is simply a prompt the awaits your command. There are several different shells, but the one used often is called “bash”, which is a mixture of a bunch of other shells.
+In cases where a program requires a GUI, you should log in using the ''–X'' option.
+This opens a tunnel to your computer allowing all windows to open in your computer.
+For this to work you need X11 installed on your computer (MobaXterm already has one)
+MAC – Xquartz (http://xquartz.macosforge.org/landing/)
+Windows – Xming (http://sourceforge.net/projects/xming/)

+Simply close the window to exit.
+====== Home Sweet Home ======
+When you first log in, you will be in a directory called “''home directory''”
+<code>
+/home/<your username>
+</code>
+Generally in this directory you have complete control over creating, modifying, and executing files in this or any sub directory you create. In order to return to your home directory simply type the command: ''cd ~'' at the prompt. Unless appropriate changes have been made you can can not enter anyone’s directory or even see what is in it.
