Getting sparse
~~~~~~~~~~~~~~
-With git, you can just get it from
+You can get latest released versions from the Sparse homepage at
+http://www.kernel.org/pub/linux/kernel/people/josh/sparse/
- rsync://rsync.kernel.org/pub/scm/devel/sparse/sparse.git
+Alternatively, you can get snapshots of the latest development version
+of sparse using git to clone..
-and DaveJ has tar-balls at
+ git://git.kernel.org/pub/scm/linux/kernel/git/josh/sparse.git
+
+DaveJ has hourly generated tarballs of the git tree available at..
