+## Running Two Applications On The Same Machine
+
+It is recommended two have one someipy application on a machine that communicates to other PCs or ECUs. But, in case you want to run two applications on the same machine, they should use different interfaces, i.e. bind to different IP addresses. If the two applications shall communicate locally, you can add another IP address to the localhost interface, e.g. 127.0.0.2.
+
+```bash
+sudo ip addr add 127.0.0.2/24 dev lo
+```
+
+Afterwards start one application working with 127.0.0.1 and the other application with 127.0.0.2:
+
+```bash
+python3 send_events_udp.py --interface_ip 127.0.0.1
+python3 receive_events_udp.py --interface_ip 127.0.0.2
+```
