Guidelines for Using Jira

What is JIRA?

What are the JIRA priorities and How to use them?

What is an Assignee and how to use it?

What are the JIRA Tags and how to use it?

Add a wiki page (if one does not exist) documenting:
  - Guidelines for writing JIRA mentioning clarity, provision of solution.
  - A clear definition of priorities (blocker, critical, major, minor,
trivial) with some examples.
  - A description of meaning of assignee and how to use it
  - A description of other metadata and how to properly use it (tags,
components, affects version, etc...)
