 DESCRIPTION

+The update-ref command(s) in the output will update the branch(es) in

+OUTPUT
+------
+
+When there are no conflicts, the output of this command is usable as
+input to `git update-ref --stdin`.  It is of the form:
+
+	update refs/heads/branch1 ${NEW_branch1_HASH} ${OLD_branch1_HASH}
+	update refs/heads/branch2 ${NEW_branch2_HASH} ${OLD_branch2_HASH}
+	update refs/heads/branch3 ${NEW_branch3_HASH} ${OLD_branch3_HASH}
+
+where the number of refs updated depends on the arguments passed and
+the shape of the history being replayed.
 
 EXIT STATUS

@@ -37,6 +61,32 @@ the replay has conflicts, the exit status is 1.  If the replay is not
 able to complete (or start) due to some kind of error, the exit status
 is something other than 0 or 1.
 
+EXAMPLES
+--------
+
+To simply rebase `mybranch` onto `target`:
+
+------------
+$ git replay --onto target origin/main..mybranch
+update refs/heads/mybranch ${NEW_mybranch_HASH} ${OLD_mybranch_HASH}
+------------
+
+When calling `git replay`, one does not need to specify a range of
+commits to replay using the syntax `A..B`; any range expression will
+do:
+
+------------
+$ git replay --onto origin/main ^base branch1 branch2 branch3
+update refs/heads/branch1 ${NEW_branch1_HASH} ${OLD_branch1_HASH}
+update refs/heads/branch2 ${NEW_branch2_HASH} ${OLD_branch2_HASH}
+update refs/heads/branch3 ${NEW_branch3_HASH} ${OLD_branch3_HASH}
+------------
+
+This will simultaneously rebase `branch1`, `branch2`, and `branch3`,
+all commits they have since `base`, playing them on top of
+`origin/main`. These three branches may have commits on top of `base`
+that they have in common, but that does not need to be the case.
