This update has mainly format related changes (no functional changes) to
improve readability when reading the non-rendered version of it.
- Use underlined style for headers level 1 and 2
- Use indentation to create blocks
- Use double space at the end of each section
- Add indentation to the FVP parameters
- Add pip command to install the kas tool

+Networking
+----------
To enable networking on the FVP via a host network interface, set up tap0 using
the following commands (Ubuntu 18.04 Host):
-```
-sudo apt-get install libvirt-bin
-sudo virsh net-start default
-sudo ip tuntap add dev tap0 mode tap user $(whoami)
-sudo ifconfig tap0 0.0.0.0 promisc up
-sudo brctl addif virbr0 tap0
-```
+
+ sudo apt-get install libvirt-bin
+ sudo virsh net-start default
+ sudo ip tuntap add dev tap0 mode tap user $(whoami)
+ sudo ifconfig tap0 0.0.0.0 promisc up
+ sudo brctl addif virbr0 tap0
+
To clean up the tap0 interface on the host use the following commands:
-```
-sudo brctl delif virbr0 tap0
-sudo ip link set virbr0 down
-sudo brctl delbr virbr0
-sudo virsh net-destroy default
-sudo ip link delete tap0
-```
+
+ sudo brctl delif virbr0 tap0
+ sudo ip link set virbr0 down
+ sudo brctl delbr virbr0
+ sudo virsh net-destroy default
+ sudo ip link delete tap0
