+electronmicroscopy/quantem.widget.

+1. Confirm `hf auth whoami` prints a username. If it fails, stop and ask me
+   to create a Write token and run `hf auth login`, or export `HF_TOKEN`.
+   Do not run an interactive login yourself or write the token into a repo.
+2. Download the checker and template, then copy the template into the folder:
+
+   hf download bobleesj/quantem-data --repo-type dataset \
+     --include "check_meta/**" --include "templates/meta.json" \
+     --local-dir ./quantem-data-tools
+   cp ./quantem-data-tools/templates/meta.json <folder>/meta.json
+
+3. Fill every required field in `<folder>/meta.json` from the files and the
+   permission lines above. Read shape and dtype from the array or EMD. Omit
+   optional values when unknown; do not invent them. Do not put a local path
+   or credential in `meta.json`. Validate it:
+
+   export PYTHONPATH="$PWD/quantem-data-tools${PYTHONPATH:+:$PYTHONPATH}"
+   python -m check_meta <folder>
+
+   Stop unless validation prints `ok`.
+4. Open the Community pull request:
+
+   hf upload bobleesj/quantem-data <folder> \
+     widget-tutorials/<widget-or-shared>/<name>/<size>/ \
+     --repo-type dataset --create-pr \

+5. Give me the Community URL. Do not merge. Open a GitHub PR only if a named
+   loader is also needed in `quantem.widget.datasets`; that PR waits until
+   this Hugging Face PR merges. A new widget is discuss-first.
