I am following instructions for installing Ubuntu Touch onto my phone, and I am at a loss for the instruction asking me to append my sources.list. Can someone please clue me in? Below is the context

The PPA has the tools and dependencies to support Precise, Quantal, and Raring. Add the Ubuntu Touch PPA by adding the following custom source list entry to your /etc/apt/sources.list file.

On your computer, press Ctrl+Alt+T to start a terminal.

sudo add-apt-repository ppa:phablet-team/tools

or if add-apt-repository is not available, append the following to your sources.list:

deb http://ppa.launchpad.net/phablet-team/tools/ubuntu [dist-codename] main
deb-src http://ppa.launchpad.net/phablet-team/tools/ubuntu [dist-codename] main

*Note: replace [dist-codename] with precise, quantal, raring or saucy.

Then do the following:

sudo apt-get update
sudo apt-get install phablet-tools android-tools-adb android-tools-fastboot

Just use the command:

sudo add-apt-repository ppa:phablet-team/tools

Thus, is not necessary to edit manually sources.list which is located in /etc/apt directory.

From https://help.ubuntu.com/community/SourcesList:

The sources.list file is a key factor in adding or upgrading applications to your Ubuntu installation. This is also used by your system for system updates. The file is basically the roadmap for your system to know where it may download programs for installation or upgrade.

Also, in the future when you hear about a file and you don't know exactly where is located, you can use the the following command ion terminal to find it:

locate file_name

It's a file that lists the 'sources' from which packages can be obtained. You can read more here: https://help.ubuntu.com/community/Repositories/CommandLine
