+you don't want to be public. With [Confidential Issues](#confidential-issues),
+you can discuss private matters among the project members, and still keep
+your project public, open to collaboration.

+All assignees are shown across your workflows and receive notifications (as they

+### Consistent collaboration

+Create [issue templates](#issue-templates) to make collaboration consistent and
