+# Companion to https://github.com/metabase/metabase/pull/81703
+# 1. Run the #81703 script first to populate the metabase branches with nav.yml files from this repo.
+# 2. Then merge all the PRs it generated.
+# 3. Then run this script to populate this feature branch with the new structure/contents.
+# 4. Then delete this file + delete _data/docs.
+# 5. Merge this branch.
+# 6. Job done. Nav data source of truth is in the metabase repo; nav.yml
+# files will get automatically copied via script/docs (and no additional
+# processing is needed since the /docs// prefixes are added in
+# getNavForVersion).
+#
+# For each version v0.44 - v0.63 plus latest (master), sparse-checkout only
+# docs/util/data/nav.yml from the metabase/metabase repo into a throwaway
+# worktree, copy that file out to _docs//util/data/nav.yml, then
+# remove the worktree.
+#
+# v0.44 - v0.63 use the release-x.NN.x branch; latest uses master.
