+Now dump any existing patch queue:

+=over 4
+
+ % git rm -rf debian/patches
+ % git commit -m "drop existing quilt patch queue"

+
+Now you simply need to ensure that your git HEAD is dgit-compatible,
+i.e., it is exactly what you would get if you ran
+B<dpkg-buildpackage -i'(?:^|/)\.git(?:/|$)' -I.git -S>
+and then unpacked the resultant source package.
+
+=for dgit-test dpkg-source-ignores end
+
+To achieve this, you might need to delete
+I<debian/source/local-options>. One way to have dgit check your
+progress is to run B<dgit build-source>.
+
+The first dgit push will require I<--overwrite>. If this is the first
+ever dgit push of the package, consider passing
+I<--deliberately-not-fast-forward> instead of I<--overwrite>. This
+avoids introducing a new origin commit into your git history. (This
+origin commit would represent the most recent non-dgit upload of the
+package, but this should already be represented in your git history.)
