   <p>
+  Hats are intended for core project developers and company employees that are
+  authorized to make comments on behalf of those organizations, and are usually
+  reserved for notable projects and organizations.  Hats are not intended to
+  list every contribution a person has made to any software project.
+  </p>
+  <p>
+  Hats will not be authorized for occasional contributors to projects,
+  developers of projects which are not widely known, past employees of
+  companies, or other situations where it cannot be verified that one is
+  authorized to represent that organization.  In general, unless one has an
+  e-mail address at a compay domain or have commit access to a project, a hat
+  will not be authorized.
+  </p>

   To request a hat for your account, provide a short description of the hat
   (e.g., "OpenBSD Developer"), a public link that will be shown when hovering
   over the hat that users can see, such as your e-mail address at that project
