 Doing a full build on your system
 ---------------------------------
 
-Following this process is equivalent to what we have set up on the
-ostree.gnome.org build server.  It will generate a completely new
-repository.

-    # installed as setuid root.

-    # http://www.yoctoproject.org/docs/current/yocto-project-qs/yocto-project-qs.html
-    # Next, we're grabbing my Poky branch.
-    
-    $ git clone git://github.com/cgwalters/poky.git
-    $ cd poky
-    $ git co gnomeos-3.6
-    $ cd $builddir

-    # to BBLAYERS.
-    #
-    # Check the conf/local.conf file and make sure "tools-profile" and
-    # "tools-testapps" are not in EXTRA_IMAGE_FEATURES
-    #
-    # Also, you should choose useful values for BB_NUMBER_THREADS and
-    # PARALLEL_MAKE

-    
-    # At the end, the Yocto build process generates two tarballs: one for
-    # a base "runtime", and one "devel" with all of the development tools
-    # like gcc.  We then import that into an OSTree branch
-    # e.g. "bases/yocto/gnomeos-3.6-i686-devel".

-    # mirrordir=/src/build/ostbuild/src
-    # workdir=/src/build/ostbuild/work

-    
-    
-    # Now we want to use the "ostbuild" binary that was created
-    # as part of "bitbake ostree-native".  You can do e.g.:
-    
-    $ export PATH=$builddir/gnomeos-build/tmp/sysroots/x86_64-linux/usr/bin:$PATH
-    
-    
-    # This next command will download all of the source code to the
-    # modules specified in $gnome-ostree/gnomeos-3.6.json, and create a
-    # file $workdir/manifest.json that has the exact git commits we want
-    # to build.
-    
-    $ ostbuild resolve --manifest /src/gnome-ostree/gnomeos-3.6.json
-    
-    
-    # By then, you should create your own prefix for the builds of the
-    # OSTree
-    
-    $ ostbuild prefix my-prefix
-    
-    
-    # This command builds everything
-    $ ostbuild build-components --src-snapshot $builddir/ostbuild/work/snapshots/gnomeos-3.6-src-snapshot-<year>.<number>-<hash>.json
+The way I have things set up, I use jhbuild to build glib,
+gobject-introspection, spidermonkey, gjs, and finally the gnome-ostree
+build system.  See install/ostree.modules.
+
+From there, just run:
+
+$ ostbuild resolve --manifest=manifest.json --fetch
+$ ostbuild build --prefix=gnomeos-3.8
