 Ansible role for clever cloud deployment
+=======
+Clever deploy
+=========
+
+This roles deploy an haskell app on clever cloud (https://www.clever-cloud.com).
+
+Requirements
+------------
+
+
+Role Variables
+--------------
+
+Variables for the application
+- `clever_token`: clever_cloud token, mandatory.
+- `clever_secret`: clever_cloud secret, mandatory.
+- `clever_app`: the id of the app to link, mandatory.
+- `clever_env`: a dict of environment variables for the application (without add_ons one already available), optional.
+- `clever_addons`: a list of dict describing addons enabled for the application from which we would use information during deploy, optional.<br/>
+  Example: `{ name: pg, env_prefix: POSTGRESQL_ADDON }`
+- `clever_app_role`: role to be executed after environment and addons variables where gathered. Specific to an app, should be use to run migrations. Optional.
+- `domain`: the domain from which the application should be reachable, optional
+- `syslog_server`: UDP Syslog server to be used as UDPSyslog drain for the application, optional. Example: `udp://198.51.100.51:12345`.
+
+Variables specific to deployment, default should be fine:
+- `clever_cli_version`: Version of clever cli tools, default to `0.9.3`.
+- `clever_user_path`: Path relative to ansible_user home dir where cli tools and helpers are installed default to `.local/bin`.
+- `clever_app_root`: Path of the application to deploy, default to `"{{ playbook_dir }}/.."`, ie ansible directory in the root of the application.
+- `clever_app_confdir`: Path where to store clever cloud data specific to this application, default to `"{{ clever_app_root }}/.clever_cloud"`
+- `clever_login_file`: Path to store login information. Default to `"{{ clever_app_confdir }}/login"`.
+
+
+Dependencies
+------------
+
+None
+
+Example Playbook
+----------------
+
+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
+      roles:
+         - { role: fretlink.clever, clever_app: 42, clever_token: "{{ vault_clever_token }}", clever_secret: "{{ vault_clever_secret}}" }
+
+
+TODO
+----
+
+Add some tests and Travis integration
