+# This add-on is deployed to a Linux container. core.autocrlf=true on the
+# authoring box gave the checkout CRLF, so a plain copy shipped CRLF files -
+# run.sh with CRLF is a "bad interpreter" failure, and any hash-based drift
+# check between repo and deployment fails for a reason that has nothing to do
+# with the code. Deploy with:
+#     git -c core.autocrlf=false archive release/1.0 goodwe_controller | tar -x
+# which is how 0.3.0 went out, byte-identical to the blobs.
