+# patchtest selftests for openembedded-core
+
+This directory provides a test suite and selftest script for use with the
+patchtest repository: https://git.yoctoproject.org/patchtest/
+
+To setup for use:
+
+1. Clone https://git.openembedded.org/openembedded-core (this repo) and https://git.openembedded.org/bitbake/
+2. Clone https://git.yoctoproject.org/patchtest
+3. Install the necessary Python modules: in meta/lib/patchtest or the patchtest
+   repo, do `pip install -r requirements.txt`
+4. Add patchtest to PATH: `export PATH=/path/to/patchtest/repo:$PATH`
+5. Initialize the environment: `source oe-init-build-env`
+6. Add meta-selftest to bblayers.conf: `bitbake-layers add-layer
+   /path/to/meta-selftest/` (the selftests use this layer's recipes as test
+   targets)
+7. Finally, run the selftest script: `./meta/lib/patchtest/selftest/selftest`
+
+For more information on using patchtest, see the patchtest repo at
+https://git.yoctoproject.org/patchtest/.
