+Fetch the Open-AVB repository and the gPTP repository:

+git clone https://github.com/Avnu/OpenAvnu.git

+To ease the further steps, enter your local copy
 and export its path and AVB interfaces via
 ```bash
 export AVB_PATH=$(pwd)
+export GPTP_PATH="$AVB_PATH/../gptp"
 export AVB_PC1_IF="eth0"
 export AVB_PC2_IF="eth2"
 ```
+Build both repositories as described in the README files.
 Then, you can use a terminal multiplexer like _byobu_ to start all needed AVB
 tools in different windows.
