-Requests for Debian software to be installed on the machines (either
-in the host system or a chroot environment) should be directed at
-debian-admin@lists.debian.org, see the instructions at
-http://dsa.debian.org/doc/install-req/ for details.
-Please note that not all software is available on all architectures. The
-chroot environments can be entered with the 'dchroot' command.
+On porter machines, the chroot environments can be entered with the
+'schroot' command, depending on setup; take a look at the list of
+machines to know which are our porterboxes. You can install build
+dependencies yourself once you instantiated a session. Please
+consult <URL:https://dsa.debian.org/doc/schroot/> for more information
+and ask your mentors if you need any help.
