PPA
Step 1
On the PPA's overview page, look for the heading that reads Adding this PPA to your system. Make a note of the PPA's location, which looks like:
ppa:gwibber-daily/ppa
Step 2
Open a terminal and enter:
sudo add-apt-repository ppa:user/ppa-name
Step 3
Now, as a one-off, you should tell your system to pull down the latest list of software from each archive it knows about, including the PPA you just added:
sudo apt-get update
Now you're ready to start installing software from the PPA!
