-The <src> side can be an

+The <src> side represents the source branch (or arbitrary
+"SHA1 expression", such as `master~4` (four parents before the
+tip of `master` branch); see linkgit:git-rev-parse[1]) that you
+want to push. The <dst> side represents the destination location.

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
+to fast forward the remote ref that matches <dst> (or, if no <dst> was
+specified, the same ref that <src> referred to locally). If
+the optional leading 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 "matching" heads are
-pushed: for every head that exists on the local side, the remote side is
-updated if a head of the same name already exists on the remote side.

`tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`.
+
A parameter <ref> without a colon pushes the <ref> from the source
+
Pushing an empty <src> allows you to delete the <dst> ref from
the remote repository.

Usually, the command refuses to update a remote ref that is
not an ancestor of the local ref used to overwrite it.
This flag disables the check. This can cause the
