+## Coding Guidelines
+
+Style guides are important because they ensure consistency in the content, look, and feel of a book or a website.
+
+* [Ansible Style Guide](http://docs.ansible.com/ansible/latest/dev_guide/style_guide/)
+* It's "Ansible" when referring to the product and ``ansible`` when referring to the command  line tool, package, etc
+* Playbooks should be written in multi-line YAML with ``key: value``. The form ``key=value`` is only for ``ansible`` ad-hoc, not for ``ansible-playbook``.
+* Tasks should always have a ``name:``
+
+## (local) Development
+
+This role make use of Molecule to test the execution of the role and verificate it. In the root of the repository, a file named `requirements.txt` exists and contains the versions used by the tests.
+
+### Requirements
+
+You can install them with the following command:
+
+```
+pip install -r requirements.txt
+```
+
+Once the dependencies are installed, please install Docker as Molecule is configured in this repository to create Docker containers. See [this](https://docs.docker.com/install/) link to install Docker on your system.
+
+### Execution
+
+Once everything is installed, you can validate your changes by executing:
+```
+molecule test
+```
+
+It should run without any issues.
+
+# Other
+
+## Virtualenv
+
+Suggestion is to create a virtualenv so you won't have issues with other projects.
+
+Some web pages describing for virtual env:

+* http://thepythonguru.com/python-virtualenv-guide/
+* https://realpython.com/python-virtual-environments-a-primer/
