+for example your RasPi IP address and port, and MongoDB URL:
+```
+export ROOT_URL=http://192.168.0.x:2000
+export PORT=2000
+export MONGO_URL='mongodb://127.0.0.1:27017/wekan'

+If you would like to run node as non-root user, and still have node at port 80, you could add capability to it, by first looking where node binary is:
+```
+which node
+```
+And then adding capability to that path of node, for example:
+```
+sudo setcap cap_net_bind_service=+ep /usr/local/bin/node
+```
+Then change to start-wekan.sh:
+```
+export ROOT_URL=http://192.168.0.x

+```
+cd bundle
+node main.js

+You need to check that it changes to correct directory, so that it can start `node main.js`
