-It can be a good idea to compare upstream's released tarballs with the
-release tags, at least for the first upload of the package. If they
-are different, you might need to add some additional steps to your
-I<debian/rules>, such as running autotools.
+The above assumes that you know how to build the package from git and
+that doing so is straightforward.
-A convenient way to perform this check is to import the tarball as
-described in the following section, using a different value for
-'upstream-tag', and then use git-diff(1) to compare the imported
-tarball to the release tag. If they are the same, you can use
-upstream's tarball instead of running git-deborig(1).
+If, as a user of the upstream source, you usually build from upstream
+tarball releases, rather than upstream git tags, you will sometimes
+find that the git tree doesn't contain everything that is in the
+tarball.
+
+Additional build steps may be needed. For example, you may need your
+I<debian/rules> to run autotools.
+
+You can compare the upstream tarball release, and upstream git tag,
+within git, by importing the tarball into git as described in the
+next section, using a different value for 'upstream-tag', and then
