+# to add a new router to the test 
+the code for this project is on janastunuc in the following folder:
+/datadrive/apps/moonlight_analytics/cowmesh-network-test
+
+in that folder is a file cowmesh_constants.py
+
+1. add the new router to NODES and HOST_TO_IP in cowmesh_constants.py with the host name and IP of the router 
+
+2. ensure that iperf2 is installed on the new router
+
+as documented here https://pad.commoninternet.net/p/cowmesh-report, there was an issue we were observing
+with installing packages via opkg (which would be the easiest way to install iperf, if it works)
+
+alternatively, I was able to avoid the opkg issue by downloading iperf2 directly from here https://downloads.openwrt.org/releases/18.06.9/packages/mips_24kc/base/ and then installing the binary directly on the router,
+by passing a path to the local downloaded file to install directly via opkg 
+
+3. on janastunuc, run: sudo systemctl restart moonlight_analytics 
+
+ideally, any changes you make to cowmesh_constants.py can also be pushed to the gitea repository (https://git.coopcloud.tech/notplants/cowmesh-network-test),
+so that gitea and the local code stay in in sync
