+## Developers: Importing from GoCardless
+
+If you clone from the github repo, you'll see a cli directory. This contains a
+script I used as a one-off to import some pre-existing GoCardless subscriptions.
+It's not a fully fledged tool but it may help others with one-off import tasks
+to build a tool for their own needs from that.
+
 ## Change log
 
+-  1.6 "stable"!
+
+   - Membership now supported thanks to work by William Mortada @wmortada and
+     Aidan Saunders @aydun, and this extension is in production use by quite a few
+     organisations so calling this release stable.
+
+   - GoCardless forms are now pre-filled with address, email, phone numbers if
+     you have collected those details before passing on to GoCardless.
+
+   - Updated GoCardlessPro library to 1.7.0 just to keep up-to-date.
+
+
 - 1.5beta Should now respect a limited number of installments. Previous
   versions will set up an open-ended subscription. You may not have wanted that
   ;-) Also updated GoCardlessPro library from 1.2.0 to 1.6.0

+/**
+ * @file
+ * This is a script provided for **developers** wanting to import existing
+ * GoCardless subscriptions into CiviCRM, e.g. if you were using GoCardless
+ * with a non-CiviCRM based system before.
+ *
+ * It is **not** ready to run, but is provided as a basis for your own import needs.
+ *
+ * You should definitely be doing this on a development copy of the site first!
+ * And you should definitely be doing backups etc. But you know that, of course you do.
+ *
+ * Nb. This will **not** work as a migration route from Veda's GoCardless extension.
+ *
+ * Run this using:
+ *
+ *     cv scr import-from-gocardless.php
+ *
+ * It loops all (100) subscriptions at GC and looks them up in CiviCRM. It will
+ * report details for any not found in CiviCRM.
+ *
+ * Assumptions and notes (**important**)
+ *
+ * - It assumes that all the customers in GoCardless can be found in CiviCRM by
+ *   looking up their email. If this is not the case either change this script or
+ *   do a separate import first.
+ *
+ * - It does not import failed payments. (You could easily change it to do this.)
+ *
