@@ -15,6 +15,15 @@ Given one existing commit, revert the change the patch introduces, and record a
 new commit that records it.  This requires your working tree to be clean (no
 modifications from the HEAD commit).
 
+Note: 'git revert' is used to record a new commit to reverse the
+effect of an earlier commit (often a faulty one).  If you want to
+throw away all uncommitted changes in your working directory, you
+should see linkgit:git-reset[1], particularly the '--hard' option.  If
+you want to extract specific files as they were in another commit, you
+should see linkgit:git-checkout[1], specifically the 'git checkout
+<commit> -- <filename>' syntax.  Take care with these alternatives as
+both will discard uncommitted changes in your working directory.
