+This directory contains example configs to use ktest for various tasks.
+The configs still need to be customized for your environment, but it
+is broken up by task which makes it easier to understand how to set up
+ktest.
+
+The configs are based off of real working configs but have been modified
+and commented to show more generic use cases that are more helpful for
+developers.
+
+crosstests.conf - this config shows an example of testing a git repo against
+    lots of different architectures. It only does build tests, but makes
+    it easy to compile test different archs. You can download the arch
+    cross compilers from:
+  https://kernel.org/pub/tools/crosstool/files/bin/x86_64/
+
+test.conf - A generic example of a config. This is based on an actual config
+     used to perform real testing.
+
+kvm.conf - A example of a config that is used to test a virtual guest running
+     on a host.
+
+snowball.conf - An example config that was used to demo ktest.pl against
+     a snowball ARM board.
+
+include/  -  The include directory holds default configs that can be
+    included into other configs. This is a real use example that shows how
+    to reuse configs for various machines or set ups. The files here
+    are included by other config files, where the other config files define
+    options and variables that will make the included config work for the
+    given environment.

+# options are described in the samples.conf file.

+#
+# The make_min_config test allows you to create a MIN_CONFIG that

+#
+# In this example, the final config will reside in

+# The second test creates a MIN_CONFIG that will only boot
+# the target and most likely will not let you ssh to it. (Notice
+# how the second test uses the first test's result to continue with.
+# This is because the second test config is a subset of the first).
+#
+# The ${CONFIG_DIR}/config-skip (and -net) will hold the configs
+# that ktest.pl found would not boot the target without them set.
+# The config-new-min holds configs that ktest.pl could not test
+# directly because another config that was needed to boot the box
+# selected them. Sometimes it is possible that this file will hold
+# the true minimum configuration. You can test to see if this is
+# the case by running the boot test with BOOT_TYPE = allnoconfig and
