Ubuntu PPA pages lack essential installation instruction

[VanillaMozilla]

The PPA pages ( example https://launchpad.net/~pmjdebruijn/+archive/ubuntu/usbguard ) all tell how to add it to software sources, but not how to install the software. There's a section "Adding this PPA to your system", but it lacks the line

sudo apt-get install package-name

(where 'package-name' is the name of the package).

If you click on the hint, "Read about installing", it doesn't actually tell you how to install. Instead it ends with the unhelpful information "Now you're ready to start installing software from the PPA!". How easy it would be to add Step 4, which of course is the missing "apt-get install" line.

This is not obvious for those of us who do this once every year or two. I personally have to research it every darned time.
