+How to get a Git repository with minimal history
+------------------------------------------------
+
+A <<def_shallow_clone,shallow clone>>, with its truncated
+history, is useful when one is interested only in recent history
+of a project and getting full history from the upstream is
+expensive.
+
+A <<def_shallow_clone,shallow clone>> is created by specifying
+the linkgit:git-clone[1] `--depth` switch. The depth can later be
+changed with the linkgit:git-fetch[1] `--depth` switch, or full
+history restored with `--unshallow`.
+
+Merging inside a <<def_shallow_clone,shallow clone>> will work as long
+as a merge base is in the recent history.
+Otherwise, it will be like merging unrelated histories and may
+have to result in huge conflicts. This limitation may make such
+a repository unsuitable to be used in merge based workflows.

The index
------------
+---------
The index is a binary file (generally kept in `.git/index`) containing a
sorted list of path names, each with permissions and the SHA-1 of a blob
Scan man pages to see if any assume more background than this manual
provides.
-Simplify beginning by suggesting disconnected head instead of
-temporary branch creation?
-
Add more good examples. Entire sections of just cookbook examples
might be a good idea; maybe make an "advanced examples" section a
standard end-of-chapter section?
Include cross-references to the glossary, where appropriate.
-Document shallow clones? See draft 1.5.0 release notes for some
-documentation.
-
Add a section on working with other version control systems, including
CVS, Subversion, and just imports of series of release tarballs.
-More details on gitweb?
-
Write a chapter on using plumbing and writing scripts.
Alternates, clone -reference, etc.
