+# Overview
+
+LCM for Juju CAAS
+
+## Testing
+
+The tests of this charm are done using tox and Zaza.
+
+
+
+### Prepare environment
+
+The machine in which the tests are run needs access to a juju k8s controller. The easiest way to approach this is by executing the following commands:
+
+```
+sudo apt install tox -y
+sudo snap install microk8s --classic
+sudo snap install juju
+
+microk8s.status --wait-ready
+microk8s.enable storage dashboard dns
+
+juju bootstrap microk8s k8s-cloud
+```
+
+If /usr/bin/python does not exist, you should probably need to do this:
+
+```
+sudo ln -s /usr/bin/python3 /usr/bin/python
+```
