General Notes

Ubuntu allows a user to accomplish tasks from either a menu-driven Graphical User Interface (GUI) or from a text-based command-line interface (CLI). In Ubuntu, the command-line-interface terminal is called Terminal, which is started: Applications -> Accessories -> Terminal.

Text inside the grey dotted box like this should be put into the command-line Terminal.

Many changes to the operating system can only be done by a User with Administrative privileges. 'sudo' elevates a User's privileges to the Administrator level temporarily (i.e. when installing programs or making changes to the system). Example:

sudo bash

'gksudo' should be used instead of 'sudo' when opening a Graphical Application through the "Run Command" dialog box. Example:

gksudo gedit /etc/apt/sources.list

"man" command can be used to find help manual for a command. For example, "man sudo" will display the manual page for the "sudo" command:

man sudo

While "apt-get" and "aptitude" are fast ways of installing programs/packages, you can also use the Synaptic Package Manager, a GUI method for installing programs/packages. Most (but not all) programs/packages available with apt-get install will also be available from the Synaptic Package Manager. In this guide, when you see

sudo apt-get install package

you can search for package in Synaptic and install it that way.

Many instructions use the text editor "nano" (which is universally available in Linux). However, it is often easier to use the text editor "gedit" in Ubuntu instead.
"Applications" means the bottom-left (or upper-left) button, akin to the Start button in Microsoft Windows.
If you are using the 64-bit version, replace any "i386" with "amd64"
