 ##How to build the host software on Linux:
 
 ###Prerequisites for Linux (Debian/Ubuntu):
-
 `sudo apt-get install build-essential cmake libusb-1.0-0-dev pkg-config libfftw3-dev`
 
 ###Build host software on Linux:
-
-`cd host`
-
-`mkdir build`
-
-`cd build`
-
-`cmake ../ -DINSTALL_UDEV_RULES=ON`
-
-`make`
-
-`sudo make install`
-
-`sudo ldconfig`
+```
+mkdir host/build
+cd host/build
+cmake ..
+make
+sudo make install
+sudo ldconfig
+```

+By defualt this will attempt to install a udev rule to '/etc/udev/rules.d` to
+provide the `usb` or `plugdev` group access to HackRF. If your setup requires
+the udev rule to be installed elsewhere you can modify the path with
+`-DUDEV_RULES_PATH=/path/to/udev`.
+
+Note: The udev rule is not installed for by default for PyBOMBS installs as
+they do not ususally get installed with root privileges.
 
 ##Clean CMake temporary files/dirs:

 ##How to build host the software on FreeBSD
-
 You can use the binary package:
 `# pkg install hackrf`
 
 You can build and install from ports:
-`# cd /usr/ports/comms/hackrf`
-`# make install`
-
+```
+# cd /usr/ports/comms/hackrf
+# make install
+```
