+# KutEx - Kubernetes to External Service
+
+This little tool helps you to replace a service with one that points to a (local) endpoint
+quickly.
+It can be helpful especially during local development, when you want services
+inside the cluster to access a local running application.
+
+## Usage
+To point a service to an external one, simply run the following command:
+
+**Please note that the existing service gets deleted during this process, so make a backup!**
+
+```
+kutex <your service name> <your endpoint ip/host>
+
+# E.g.
+kutex superservice 192.168.64.1
+```
