Cinder Contributor Documentation (source/contributor)
Introduction:
This directory is intended to hold any documentation that relates to how to contribute to Cinder or how the project is managed. Some of this content was previous under 'developer' in openstack-manuals. The content of the documentation, however, goes beyond just developers to anyone contributing to the project, thus the change in naming.
The full spec for organization of documentation may be seen in the OS Manuals Migration Spec <https://specs.openstack.org/openstack/docs-specs/specs/pike/os-manuals-migration.html>.
