+Thunderbird extension for the Todo.txt application. This extension tries to integrate the [Todo.txt](http://todotxt.com/) application with Thunderbird. Using the Lightning extension it is now possible to add, delete or modify todo's directly within Thunderbird.
 
 ## Functionality
 
 * Add, delete or modify Todo's from within your Thunderbird
 * Automatically use Thunderbirds functions from Todo.txt, such as categories and priorities.
 * Get a quick overview of all your tasks.
 * Search for complete and incomplete Todo's within Thunderbird using search paramaters such as Contexts or Projects.
+* Use Todo.txt's syntax directly within Thunderbird.
+
+# Usage
+
+The extension requires the following options:
+
+1. Location of your Todo.txt file
+2. Location of your Done.txt file
+
+After this configuration it is possible to see al finished and incomplete tasks and add, delete or modify them accordingly. 
+
+**Todo.txt works best with a synchronisation application such as Dropbox or Owncloud, in order to prevent accidental overwriting of the file it might be usefull to set the refresh time of the calendar to a couple of minutes**
+
+## Syntax
+
+The extension can automatically assign the appropiate properties to a Thunderbird task based on the Todo.txt syntax. This means that when a user enters a new Task with Todo.txt syntax it will result in a correct Thunderbird task.
+
+For example:
+`(A) foobar +Dev +Home @PR`
+
+Entered as a new task within Thunderbird, it will automatically have the following properties:
+* High priority
+* Categories set to DEV & Home
+* Title containing *foobar @PR*
+
+Offcourse the Todo.txt file will contain the extact line as entered into Thunderbird.
