I have a Dell E5450, and Dell offers some driver packages.
I have downloaded a houston-15_A10.fish.tar.gz, and extracted it:
$ tar -xvzf houston-15_A10.fish.tar.gz
And then the folder contains:

Yet I am missing a README as I have no clue how to proceed and what to do next.
The installation guide is of no help either, as it assumes that one uses the Dell Ubuntu image:
Installation instructions 1) Download the latest Dell Ubuntu image from http://goo.gl/s4Atrh.
2) Create a bootable USB stick or DVD with the Dell Ubuntu image.
Yet I have used the default Ubuntu 14.04 image and wanted to now install the drivers. I don't want to do yet another Ubuntu installation with Dell's image, which even seems to only be 12.04.
How do I install the driver package?
