+1. Fork the repo
+
+2. Create a branch and apply your changes to this branch.
+
+    a. Make sure you have updated the documentation when adding new variables;
+    
+    b. Don't forget to add/update tests so we can test the functionality during each Pull Request;

+* [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

+## (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.

+### Supported systems
+This role supports the following systems:
 
-No requirements. (Yes, an Influxdb server somewhere on the network will help though ;-) )
+ * Red Hat
+ * Debian
+ * Ubuntu
+ * Docker container
+ * Windows (Best effort)
+ * (Open)Suse
+
+So, you'll need one of those systems.. :-)
+Please sent Pull Requests or suggestions when you want to use this role for other systems.
+
+### InfluxDB
+
+You'll need an InfluxDB instance running somewhere on your network. Or 1 of the other output types found on https://github.com/influxdata/telegraf/#output-plugins
+
+### Docker
+
+Docker needs to be installed on the target host. I can recommend these roles to install Docker:

+* [jgeusebroek.docker](https://galaxy.ansible.com/jgeusebroek/docker)
+* [geerlingguy.docker](https://galaxy.ansible.com/geerlingguy/docker)

+* `telegraf_agent_aws_tags`: Configure AWS ec2 tags into Telegraf tags section Default: `False`
+* `telegraf_agent_aws_tags_prefix`: Define a prefix for AWS ec2 tags. Default: `""`
 * `telegraf_agent_collection_jitter`: Jitter the collection by a random amount. Default: 0 (since v0.13)
 * `telegraf_agent_metric_batch_size`: The agent metric batch size. Default: 1000  (since v0.13)
 * `telegraf_agent_metric_buffer_limit`: The agent metric buffer limit. Default: 10000  (since v0.13)

 Telegraf plugin options:
 
 * `tags` An k/v tags to apply to a specific input's measurements. Can be used on any stage for better filtering for example in outputs.
-* `pass`: An array of strings that is used to filter metrics generated by the current plugin. Each string in the array is tested as a prefix against metric names and if it matches, the metric is emitted.
-* `drop`: The inverse of pass, if a metric name matches, it is not emitted.
 * `tagpass`: (added in Telegraf 0.1.5) tag names and arrays of strings that are used to filter metrics by the current plugin. Each string in the array is tested as an exact match against the tag name, and if it matches the metric is emitted.
 * `tagdrop`: (added in Telegraf 0.1.5) The inverse of tagpass. If a tag matches, the metric is not emitted. This is tested on metrics that have passed the tagpass test.
 * `interval`: How often to gather this metric. Normal plugins use a single global interval, but if one particular plugin should be run less or more often, you can configure that here.
