 # WillowSword
 A Ruby on Rails engine for the Sword V2 server. The Sword server is currently integrated with Hyrax V2.
 
+This code is derived from the original Willow Sword gem, via a fork maintained at https://github.com/tomwrobel/willow_sword
+
+On that branch, the equivalent of master here is feature/ora_customizations
+
 ## Important note for ORA users
 
-This project uses git flow conventions for code management, with a major wrinkle: 
-the production/master branch of this code is feature/ora_customizations
+This project uses git flow conventions for code management.
 
 The development branch is still develop, and the release branches are tagged release/ as normal.
 
-The major/minor version numbers of releases will follow the Hyrax/ora.reviewinterface version 
-number that corresponds to the release cycle under which they were released, e.g. release v3.4.0 will correspond
-to ora4.reviewinteface's v3.4.0 release. If no updates to the Sword gem are being released at the time of
-an ora4.reviewinterface release, then that version will be skipped in Sword, e.g. if a new version of the Sword gem is being released with 
-ora4.reviewinterface v3.7.0, then the Sword gem version will be v3.7.0, even if there was no v3.6.0. 
-
-This means that release numbers will not necessarily be sequential, as the number does not have 
-to be updated unless code has been updated. 
-
-Hotfix/bugfix version numbers may not directly correspond (e.g. v3.4.1 vs v3.4.2). 
+New versions will be tagged from v5.0.0
 
 ## Deployment to ORA4 QA
 
 At present, we have no way to configure that branch used in the ora4.reviewinterface gemfile. Therefore a release
 into QA should be followed by an update to the ora4-qa-symp gemfile from 
 
 ```ruby
-gem 'willow_sword', git: 'https://github.com/tomwrobel/willow_sword', branch: 'feature/ora_customizations'
+gem 'willow_sword', git: 'https://gitlab.bodleian.ox.ac.uk/ORA4/willow_sword', branch: 'develop'
 ```
 
 To
 
 ```ruby
-gem 'willow_sword', git: 'https://github.com/tomwrobel/willow_sword', branch: 'develop'
+gem 'willow_sword', git: 'https://gitlab.bodleian.ox.ac.uk/ORA4/willow_sword', branch: 'working_branch'
 ```
 
-(amend develop to release/v{release number} as appropriate). And a bundle update and apache reboot should be run.
