+# This script generates command documentation by downloading the oras command
+# and parsing the help text to generate documentation. It iterates over the
+# `versions.json` file to determine the releases that are currently supported.
+#
+# If there is a fix to the help documentation in a patch version, use the
+# `versions-latest` file to specify the patch release for document generation.
+#
+# For example, If you are generating documentation for `1.2` and you want to
+# use `1.2.2` to generate the documentation, put a line in the `versions-latest`
+# file `1.2.2`.  If there is no line in the `versions-latest` that matches
+# the major and minor release `1.2`, then `1.2.0` will be used to generate
+# the documentation.
