+
+This role sets the default web browser for Ubuntu Unity and Xfce4.
 
 Requirements
 ------------
 
-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.

+
+* Ubuntu
+
+    * Trusty (14.04)
+    * Wily (15.10)
+    * Xenial (16.04)
+    * Note: other Ubuntu versions are likely to work but have not been tested.
+
+* Supported desktop
+
+    * Ubuntu Unity (i.e. the default desktop on Ubuntu)
+
+        Note: other Gnome based desktops may work but have not been tested.
+
+    * Xfce4 (i.e. the desktop on XUbuntu)

 --------------
 
-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.

+```
 
 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:
+```yaml
+- hosts: servers
+  roles:
+    - role: gantsign.default-web-browser
+      default_web_browser: google-chrome
+```
 
-    - hosts: servers
-      roles:
-         - { role: username.rolename, x: 42 }
