 talm -n 1.2.3.4 -e 1.2.3.4 template -t templates/controlplane.yaml -i > nodes/node1.yaml
 ```
 
+If you are testing template rendering you can pass the flag --offline. Also using the --full flag will generate a complete configuration, usefull for testing proper rendering of the templates.
+```bash
+talm template -t templates/controlplane.yaml --offline --full -i > nodes/cp1.yaml
+talm template -t templates/worker.yaml --offline --full -i > nodes/worker1.yaml
+```
+
+To develop and extend templates capabilities of talm you can use make render-template to render templates offline and check the output:
+```bash
+make render-template SET_ARGS="--set kubespan=false --full"
+```
