THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
Creating a repo is self-service, but pay attention and change the default configuration of the notifications so that email goes to issues@openwhisk.apache.org and not to dev@openwhisk.apache.org. Also note that the tool will automatically inject "openwhisk" into the repo name, so don't do it yourself and get a redundantly long name.
You create the repo here https://gitbox.apache.org/setup/newrepo.html.
After the repo is created, you need to enable it for TravisCI.
After that is done, you need to open an INFRA JIRA ticket to get it properly configured. For an example ticket, look here: https://issues.apache.org/jira/browse/INFRA-17095
