+Drupal 7 module for managing event bookings. Originally designed for use with the biennial Christadelphian event known as Study Week.
 
-To install:
+## Pre-installation
+Before installation, download and install the following pre-requisite modules:
+- [libraries](http://drupal.org/project/libraries) module
+- [token](http://drupal.org/project/token) module
+- [date](http://drupal.org/project/date) module
+- [mimemail](http://drupal.org/project/mimemail) module
+- [mailsystem](http://drupal.org/project/mailsystem) module
+
+If you plan to use Stripe for payment integration, download the [Stripe API Library for PHP](https://github.com/stripe/stripe-php) and install in your sites libraries folder (usually sites/all/libraries). The folder should be renamed to stripe (ie sites/all/libraries/stripe/lib/Stripe.php).
+
+## Installation
 - Clone (or download & unpack) this module into your site's module directory (usually sites/all/modules)
-- If not installed, download the [libraries](http://drupal.org/project/libraries) module, the [token](http://drupal.org/project/token) module and the [date](http://drupal.org/project/date) module
-- Download the [Stripe API Library for PHP](https://stripe.com/docs/libraries) and install in your sites libraries folder (usually sites/all/libraries). The folder should be renamed to stripe (ie sites/all/libraries/stripe/lib/Stripe.php).
 - Enable the booking module, and visit the [configuration page](http://your.site.com/admin/config/booking/general) to set initial values and save prior to using module
+
+## Configuration
+In addition to the main configuration page, you will need to set up [text definitions](http://your.site.com/admin/config/booking/text) for various built-in pages, as well as update [email definitions](http://your.site.com/admin/config/booking/emails)  for automatically generated emails.
