+Buy Courses (course sales) plugin
+=================================
+This plugin transforms your Chamilo installation in an online shop by adding a catalogue
+ of courses and sessions that you have previously configured for sales.
+
+If the user is not registered or logged in, he/she will be requested to register/login
+before he/she can resume buying items.
+
+Do not enable this plugin in any "Region". This is a known issue, but it works without 
+region assignation.
+
+Once the course or session is chosen, the plugin displays the available payment methods
+and lets the user proceed with the purchase.
+Currently, the plugin allows users to pay through:
+ - PayPal (requires a merchant account on PayPal at configuration time)
+ - Bank payments (requires manual confirmation of payments' reception)
+ - RedSys payments (Spanish payment gateway) (requires the download of an external file)
+ - Stripe payments (requieres a merchant account oin Stripe at configuration time)
+ - Cecabank payments (Spanish payment gateway)
+
+The user receives an e-mail confirming the purchase and she/he can immediately 
+access to the course or session.
+
+We recommend using sessions as this gives you more time-related availability options
+(in the session configuration).
+
+Updates
+=========
+
+You must load the update.php script for installations that were in 
+production before updating the code, as it will update the database structure to
+enable new features.
+
+Please note that updating Chamilo does *NOT* automatically update the plugins
+structure.
+
+You can find a history of changes in the [CHANGELOG.md file](../../plugin/buycourses/CHANGELOG.md)
