 NAME
 ----
-git-show - Show one commit with difference it introduces
+git-show - Show various types of objects
 
 
 SYNOPSIS
 --------
-'git-show' <option>...
+'git-show' [options] <object>...
 
 DESCRIPTION
 -----------
-Shows commit log and textual diff for a single commit.  The
-command internally invokes 'git-rev-list' piped to
-'git-diff-tree', and takes command line options for both of
-these commands. It also presents the merge commit in a special
-format as produced by 'git-diff-tree --cc'.
+Shows one or more objects (blobs, trees, tags and commits).
+
+For commits it shows the log message and textual diff. It also
+presents the merge commit in a special format as produced by
+'git-diff-tree --cc'.
+
+For tags, it shows the tag message and the referenced objects.
+
+For trees, it shows the names (equivalent to gitlink:git-ls-tree[1]
+with \--name-only).
+
+For plain blobs, it shows the plain contents.
 
 This manual page describes only the most frequently used options.
