    The chain of trust in Debian starts when a maintainer uploads a new
-   package or a new version of a package to the Debian archive. This
-   upload in order to become effective needs to be signed by a key of
-   a maintainer within the Debian maintainer's keyring (available in
-   the debian-keyring package). Maintainer's keys are signed by
+   package or a new version of a package to the Debian archive. In
+   order to become effective, this upload needs to be signed by a key
+   contained in the Debian Maintainers keyring (available in
+   the debian-keyring package). Maintainers' keys are signed by
    other maintainers following pre-established procedures to
    ensure the identity of the key holder.

    Once the uploaded package is verified and included in the archive,
-   the maintainer signature is stripped off, an MD5 sum of the package
-   is computed and put in the Packages file. The MD5 sum of all of the
-   packages files are then computed and put into the Release file. The
-   Release file is then signed by the archive key (which is created
-   once a year) and distributed through the FTP server. This key is
-   also on the Debian keyring.

+   and distributed alongside the packages and the Packages files on
