+Aufs3 -- advanced multi layered unification filesystem version 3.x
+http://aufs.sf.net
+
+For (an unreleased) example:
+If you are using "linux-3.10" and the "aufs3.10" branch
-+does not exit in aufs-util repository, then "aufs3.9", "aufs3.8"
++does not exist in aufs-util repository, then "aufs3.9", "aufs3.8"
+or something numerically smaller is the branch for your kernel.
+
+Also you can view all branches by
+ =m or =y.
+- and build your kernel as usual.
+- install the built kernel.
-+- install the header files too by "make headers_install".
++- install the header files too by "make headers_install" to the
++ directory where you specify. By default, it is $PWD/usr.
+- and reboot your system.
+
+2.
+ ./aufs.ko to /lib/modules/... and run depmod -a (or reboot simply).
+ + run "make headers_install" to install the aufs header file (you can
+ specify DESTDIR), or copty ./usr/include/linux/aufs_type.h to
-+ /usr/include/linux or wherever you like.
++ /usr/include/linux or wherever you like. By default, the target
++ directory is $PWD/usr.
+- no need to apply aufs3-kbuild.patch, nor copying source files to your
+ kernel source tree.
+
+Pavel Pronskiy made a donation (2011/2).
+Iridium and Inmarsat satellite phone retailer (www.mailasail.com), Nippy
+ Networks (Ed Wildgoose) made a donation for hardware (2011/3).
-+Max Lekomcev (DOM-TV project) made a donation (2011/7).
++Max Lekomcev (DOM-TV project) made a donation (2011/7, 12 and 2012/3).
