+These instructions were written and tested for both Ubuntu 12.04LTS and Ubuntu 14.04LTS.  You will also need to be familiar with terminal use.
+
+**Preparing Your System**
+
+First things first, make sure all your current software is up to date<br>
+`$sudo apt-get update`<br>
+`$sudo apt-get upgrade -y`
+
+**Installing GNU Radio**
+
+1. Create a directory to hold all the files needed to build the supporting software. In this example we will create a directory called **hackrf_files** under our home folder:<br>
+`$mkdir ~/hackrf_files`
+2. Download a copy of Marcus D. Leech's fantastic GNU radio setup script.  You can find it here:<br> http://www.sbrac.org/files/build-gnuradio
+3. Save the script to ~/hackrf_files/build-gnuradio.sh
+4. Give the script execution permission<br>
+`$chmod 744 ~/hackrf_files/build-gnuradio.sh`
+5. Execute the script using ~/hackrf_files/build-gnuradio.sh and follow the prompts<br>**WARNING: This step may very well take a few hours to complete!**
+
+**Installing HackRF Tools**
+
+If you used the above steps to install GNU Radio, simply do the following to build and install the HackRF tools:<br>
+`$cd ~/hackrf_files/hackrf/host/hackrf-tools && mkdir build && cd build && cmake .. && make && sudo make install`
