+<repository>::
+       The "remote" repository that is destination of a push
+       operation.  See the section <<URLS,GIT URLS>> below.
+
+<refspec>::
+       The canonical format of a <refspec> parameter is
+       `+?<src>:<dst>`; that is, an optional plus `+`, followed
+       by the source ref, followed by a colon `:`, followed by
+       the destination ref.
++
+The <src> side can be an
+arbitrary "SHA1 expression" that can be used as an
+argument to `git-cat-file -t`.  E.g. `master~4` (push
+four parents before the current master head).
++
+The local ref that matches <src> is used
+to fast forward the remote ref that matches <dst>.  If
+the optional plus `+` is used, the remote ref is updated
+even if it does not result in a fast forward update.
++
+Note: If no explicit refspec is found, (that is neither
+on the command line nor in any Push line of the
+corresponding remotes file---see below), then all the
+refs that exist both on the local side and on the remote
+side are updated.
++
+Some short-cut notations are also supported.
++
+* `tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`.
+* A parameter <ref> without a colon is equivalent to
+  <ref>`:`<ref>, hence updates <ref> in the destination from <ref>
+  in the source.
