 ## Board meeting tools  {#tools}
 
-With the creation of the [Apache Whimsy project](https://whimsy.apache.org/), we now have a number of 
-tools that aid in creation and management of the agenda; workflow 
-functions for submitting, commenting, and approving reports; and a handy, 
-categorized view of the current agenda and the minutes of past meetings.
-
-While most Whimsy features are restricted to Apache Committers (and much of
-that is further restricted to Members, Officers, or even a specific officer),
-the [categorized listing of past board minutes](https://whimsy.apache.org/board/minutes/)
-is public.  This allows anyone to easily review all past board meetings by
-date, by PMC, or by major special resolutions.  We provide this access as a convenience. The official/canonical version of this data is

+The board prepares, runs and records its meetings in the [Board Agenda Tool][2], which is
+maintained by the [Apache Tooling project](https://tooling.apache.org/).  It replaces the
+agenda tool that the [Apache Whimsy project](https://whimsy.apache.org/) used to provide.
+
+An agenda is still a plain text file in the foundation's private SVN repository, and the
+tool commits to it in the name of whoever made the change - so command line users can
+carry on as before.  What the tool adds is the workflow around that file:
+
+- it **assembles each month's agenda** a day or so after the previous meeting, from the
+  board calendar, the reporting schedule in `committee-info.txt` and the business the last
+  meeting left open, and assigns each project report a Shepherd;
+- PMC Chairs and officers **post their reports** into it, and it sends the reminders that
+  chase the ones that have not arrived;
+- directors **pre-approve, flag and comment on** reports before the meeting, and raise
+  action items;
+- the Chair runs the live meeting from it, and everyone attending can follow along on
+  their own screen at whatever item the Chair has reached;
+- the Secretary **records the minutes** in it as the meeting goes, and afterwards works
+  through a checklist of what the meeting decided - mailing the summary, carrying out
+  resolutions, and publishing the minutes the board approved.
+
+An Apache login is required, and what you can see and do follows the roles you hold: ASF
+Members and PMC Chairs can read the agenda, while pre-approving reports, running the
+meeting and recording the minutes belong to the directors, the Chair and the Secretary
+respectively.  The tool's own [documentation page](https://agenda.apache.org/documentation)
+sets all of that out role by role.
+
+Past minutes are public and need no login.  The official, canonical publication is our
+[formal publication of all past board meeting minutes](/foundation/board/calendar.html).
+Whimsy additionally offers a
+[categorized listing of past board minutes](https://whimsy.apache.org/board/minutes/),
+which lets anyone review past meetings by date, by PMC, or by major special resolutions;
+we provide that as a convenience, and it is being moved onto this site.
