How to keep an open source project enterprise ready The talk will show what happen when a new version of openSUSE is released and more fixes and updates are starting to be delivered via the maintenance process. During this introduction the attendees will be able to understand how the teamwork efforts of the openSUSE community and SUSE allow the delivering of a great open source distribution. Always following the open source knowledge sharing approach, the attendees will be made aware of key information for starting to contribute to the project with a particular focus on the area of packaging and testing.
