-# Debian virtwl-patched wayland clients
+# (OBSOLETE) Debian virtwl-patched wayland clients
 
 ## Overview
+These packages are no longer needed with sommelier.
+
 These are Debian source packages that have been patched to support virtwl
 shmem allocation.
-
-## Building
-Local builds can be performed by executing kokoro/build.sh. This will use
-cowbuilder to build the source package after installing the virtwl kernel
-header.
-
-Release builds can be run through kokoro.
-
-## Updating
-It's highly recommended to use a disposable container (Docker or lxd works)
-of the target distro to work on.
-
-The source packages here were generated by doing the following, on the distro
-to update:
-
-```sh
-# Install dependencies.
-sudo apt-get install build-essential devscripts quilt
-
-# Put virtwl header in the right spot.
-sudo install -m 644 patches/virtwl.h /usr/include/linux/virtwl.h
-
-# Get source.
-apt-get source $PACKAGE
-cd $PACKAGE-$VERSION
-
-export QUILT_PATCHES=debian/patches
-mkdir -p "${QUILT_PATCHES}"
-
-# Import each patch with quilt.
-QUILT_PATCHES=debian/patches quilt import ../../patches/$PACKAGE/0001-...
-QUILT_PATCHES=debian/patches quilt import ../../patches/$PACKAGE/0002-...
-
-# Apply patches to current source tree.
-QUILT_PATCHES=debian/patches quilt push -a
-
-# Build the source and binary packages.
-dpkg-buildpackage --sign-key=<your gpg key>
-```
-
-Test only the binary package on an existing container to check compatibility.
-Then, commit only the source package, which should contain only the following
-files:
-
-* package\_version.orig.tar.xz
-* package\_version-debver.debian.tar.xz
-* package\_version-debver.dsc
