 ## Installation
 
@@ -20,8 +20,16 @@ To do this, Ctrl-Click on the binary and select "allow".
 
 ## Usage
 
-Run `kc` to switch to a Kubernetes context. You can either directly specify the context to switch to or leave it empty
-to select from a list of contexts from the kubeconfig file.
+Run `kubectl cs` to switch to a Kubernetes context and/or namespace. You can directly specify the context to switch to
+in the form of `context:namespace`. If you leave either of the two parts empty, it will only change the remaining part.
+
+Examples:
+
+* `kubectl cs int:` - Switch to the currently active namespace in the `int` context
+* `kubectl cs :kube-system` - Switch to the namespace `kube-system` in the currently active context
+* `kubectl cs int:kube-system` - Switch to the namespace `kube-system` in the `int` context
+
+If you don't specify anything, `kubectl cs` will present a selection list of all namespaces in all contexts, which can
+be filtered and selected. If that takes too long, the flag `--only-current-context` can be used, which only enumerates
+the namespaces of the current context.
 
-Run `kc -n` to switch the default namespace for the current context. You can either directly specify the namespace
-to switch to or leave it empty to select from a list of namespaces available to you.
