+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at [labs@idealista.com](mailto:labs@idealista.com). All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.

+## Getting Started
+
+These instructions will get you a copy of the role for your ansible playbook. Once launched, it will install an Apache ZooKeeper server.
+
+### Prerequisities
+
+Ansible 2.5.3.0 version installed.
+Molecule 2.19.0 version installed.
+
+Inventory destination should be a Debian environment.
+
+Notice that automatically java is installed as dependency.
+
+For testing purposes, [Molecule](https://molecule.readthedocs.io/) with [Docker](https://www.docker.com/) as driver
+
+### Installing
+
+Create or add to your roles dependency file (e.g requirements.yml):
+
+```
+- src: idealista.zookeeper-role
+  version: 1.3.0
+  name: zookeeper
+```
+
+Install the role with ansible-galaxy command:
+
+```
+ansible-galaxy install -p roles -r requirements.yml -f
+```
+
+Use in a playbook:
+
+```
+---
+- hosts: someserver
+  roles:
+    - {
+				role: zookeeper
+      }
+```
+
+## Usage
+
+To set multiple versions
+
+```
+zookeeper_hosts:
+  - host: zookeeper1
+    id: 1
+  - host: zookeeper2
+    id: 2
+  - host: zookeeper3
+    id: 3
+```
+
+## Testing
+
+
+```sh
+$ pipenv install -r test-requirements.txt --python 2.7
