A brief description of the role goes here.
4+
[![Build Status](https://travis-ci.org/adriagalin/ansible.neo4j.svg?branch=master)](https://travis-ci.org/adriagalin/ansible.neo4j) [![Ansible Galaxy](http://img.shields.io/badge/ansible--galaxy-neo4j-blue.svg)](https://galaxy.ansible.com/list#/roles/NUM)

Requirements
79
------------
810

9-
Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.
11+
Tested on:
12+
13+
- Ubuntu 14.04 LTS
14+
- Ubuntu 16.04 LTS
15+
16+
Should work with:
17+
18+
- All Ubuntu
19+
- All Debian

Role Variables
1222
--------------
1323

14-
A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
24+
Check defaults/main.yml file to review all vars.

Dependencies

------------

19-
A list of other roles hosted on Galaxy should go here, plus any details in regards to parameters that may need to be set for other roles, or variables that are used from other roles.
29+
None.

Example Playbook

----------------
2333

24-
Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: servers
34+
```yaml
35+
- hosts: all

roles:
28-
- { role: username.rolename, x: 42 }
37+
- { role: adriagalin.neo4j }

Inspiration
