-# Adapted from https://github.com/pydata/xarray/blob/main/.github/workflows/upstream-dev-ci.yaml
+# This configures a github action that runs the JAX test suite against nightly development builds
+# of numpy and scipy, in order to catch issues with new package versions prior to their release.
+# Unlike our other CI, this is one that we expect to fail frequently, and so we don't run it against
+# every commit and PR in the repository. Rather, we run it on a schedule, and failures lead to an
+# issue being created or updated.
