 ## JIRA
 
-Bugs and features against Sakai are tracked in our [JIRA instance](https://jira.sakaiproject.org/) and contributions must reflect a JIRA reference number in the messages and git branch names (e.g., SAK-29469), but please don't put these references in the code as over time files become full of them and the same information get be retrieved from git. To file or comment on a bug or feature, you will need a JIRA account.
