 to the TC and the TC uses its standard consensus seeking process to evaluate whether or
 not to add this new member. Members who do not participate consistently at the level of

+# Project Captains
+
+The Express TC can designate captains for individual projects/repos in the
+organizations. These captains are responsible for being the primary
+day-to-day maintainers of the repo on a technical and community front.
+Repo captains are empowered with repo ownership and module publication rights.
+When there are conflicts, especially on topics that effect the Express project
+at large, captains are responsible to bring it up with the TC and drive
+those conflicts to resolution. Captains are also responsible in making sure
+community members follow the community guidelines, maintaining the repo
+and the registry, as well as in providing user support.
+
+Like TC members, Repo captains are a subset of committers.
+
+To become a captain for a project the candidate is expected to participate in that
+project for at least 6 months prior to the request. They should have helped with
+code contributions as well as triaging issues. They are also required to have 2FA
+enabled on both their GitHub and npm accounts. When they want to request the
+captain role, submit a PR to this doc, under `Current Project Captains` section
+(maintaining the sort order) with the project, their GitHub handle and npm username.
+The PR will require at least 2 approvals from TC members and 2 weeks hold time to
+allow for comment.  When the PR is merged, a TC member will add them to the proper
+GitHub groups, as well as grant their npm publish rights.
