+## Changing sysctl variables
+
+If you want to overwrite sysctl-variables, you have to overwrite the *whole* dict, or else only the single overwritten will be actually used.
+So for example if you want to change the IPv4 traffic forwarding variable to `1`, you must pass the whole dict like this:
+
+```
+    - hosts: localhost
+      roles:
+        - dev-sec.os-hardening

+
+Alternatively you can change Ansible's [hash-behaviour](https://docs.ansible.com/ansible/intro_configuration.html#hash-behaviour) to `merge`, then you only have to overwrite the single hash you need to. But please be aware that changing the hash-behaviour changes it for all your playbooks and is not recommended by Ansible.
 
 ## Local Testing
 
-For local testing you can use vagrant and Virtualbox of VMWare to run tests locally. You will have to install Virtualbox and Vagrant on your system. See [Vagrant Downloads](http://downloads.vagrantup.com/) for a vagrant package suitable for your system. For all our tests we use `test-kitchen`. If you are not familiar with `test-kitchen` please have a look at [their guide](http://kitchen.ci/docs/getting-started).
+The preferred way of locally testing the role is to use Docker. You will have to install Docker on your system. See [Get started](https://docs.docker.com/) for a Docker package suitable to for your system.
