 Straightforward usage, to run the simple strategy:
 
 ```sh
-python krr.py simple
+krr simple
 ```
 
 If you want only specific namespaces (default and ingress-nginx):
 
 ```sh
-python krr.py simple -n default -n ingress-nginx
+krr simple -n default -n ingress-nginx
 ```
 
 By default krr will run in the current context. If you want to run it in a different context:
 
 ```sh
-python krr.py simple -c my-cluster-1 -c my-cluster-2
+krr simple -c my-cluster-1 -c my-cluster-2
 ```
 
 If you want to get the output in JSON format (--logtostderr is required so no logs go to the result file):
 
 ```sh
-python krr.py simple --logtostderr -f json > result.json
+krr simple --logtostderr -f json > result.json
 ```
 
 If you want to get the output in YAML format:
 
 ```sh
-python krr.py simple --logtostderr -f yaml > result.yaml
+krr simple --logtostderr -f yaml > result.yaml
 ```
 
 If you want to see additional debug logs:
 
 ```sh
-python krr.py simple -v
+krr simple -v
 ```
