+$ git reset --hard HEAD~3 <2>
+$ git checkout topic/wip <3>
+
+<1> You have made some commits, but realize they were premature

+
+<1> you are happily working on something, and find the changes
+in these files are in good order.  You do not want to see them
+when you run "git diff", because you plan to work on other files
+and changes with these files are distracting.
+<2> somebody asks you to pull, and the changes sounds worthy of merging.
+<3> however, you already dirtied the index (i.e. your index does
+not match the HEAD commit).  But you know the pull you are going
+to make does not affect frotz.c nor filfre.c, so you revert the
+index changes for these two files.  Your changes in working tree
+remain there.

+NOT LEARNING CORE GIT COMMANDS
+------------------------------
+
+This manual is intended to give complete background information
+and internal workings of git, which may be too much for most
+people.  The <<Discussion>> section below contains much useful
+definition and clarification - read that first.
+
+If you are interested in using git to manage (version control)
 projects, use link:everyday.html[Everyday GIT] as a guide to the
 minimum set of commands you need to know for day-to-day work.
+Most likely, that will get you started, and you can go a long
+way without knowing the low level details too much.
+
+The link:tutorial.html[tutorial] document covers how things
+internally work.
+
+If you are migrating from CVS, link:cvs-migration.html[cvs
+migration] document may be helpful after you finish the
+tutorial.
 
 After you get the general feel from the tutorial and this
 overview page, you may want to take a look at the
 link:howto-index.html[howto] documents.

+CORE GIT COMMANDS
+-----------------
+
 If you are writing your own Porcelain, you need to be familiar
 with most of the low level commands --- I suggest starting from
 gitlink:git-update-index[1] and gitlink:git-read-tree[1].
