 command combines these steps.
 
+\subsection{Sharing your patches}
+
+You may sometimes need to share your patches with someone else, or 
+reapply them on another instance of your software. As quilt patches are all
+contained in the \textsf{patches} directory, you just need to distribute 
+this directory, making sure your patches are properly refreshed.
+You can also export all your patches in a single patch file using
+\quilt{diff --combine}.
+
+\subsection{Merging with upstream}
+
+The concept of merging your patches with upstream is identical to applying
+your patches on a more recent version of the software. 
+
+First, make sure to pop all your patches using \quilt{pop -a}. Then update
+your codebase. Finally remove the obsoleted patches and \quilt{push} all
+remaining ones, refreshing and fixing those in need.
