    Bug 33952: Add instructions related to build-sunet-a.torproject.net
    
    Add instructions for adding/removing/updating users on
    build-sunet-a.torproject.net as well as installing new packages.
    
    We also update the tbb-team role to make it possible to remove users.
    
    While updating the README file we also add a link for more details about
    setting up a new nightly build machine.

+Adding, removing, updating users on the Tor Browser team build machine
+======================================================================
+
+The tbb-build.yml playbook is used to set up the Tor Browser team build
+machine (build-sunet-a.torproject.net).
+
+To add a new user:
+
+ - add the new username to roles/tbb-team/defaults/main.yml
+ - add the ssh key file to roles/tbb-team/files/${username}.pub
+ - run "make ansible-tbb-build"
+
+To update the ssh key for an existing user:
+ - update roles/tbb-team/files/${username}.pub
+ - run "make ansible-tbb-build"
+
+To remove a user and their home directory from the build machine:
+ - in roles/tbb-team/defaults/main.yml, move the user from
+   tbb_team_members to tbb_team_alums
+ - remove roles/tbb-team/files/${username}.pub
+ - run "make ansible-tbb-build"
+
+To install additional packages you can add them to
+roles/tbb-builder/tasks/main.yml if they are necessary to build
+Tor Browser, or to roles/useful-packages/tasks/main.yml otherwise.
+
+If you don't want to apply the changes directly, but first want to check
+what would be the changes done by ansible, you can edit the ansible-playbook
+command in the Makefile to add the --check argument.
