+Generate release changelog artifacts for one ATT&CK version pair:
+
+```shell
+attack_changelog --old-version 17.1 --new-version 18.0
+```
+
+The `attack_changelog` command reads local release data from `attack-releases/stix-2.0/v{version}` by default.
+If either requested release is missing, it downloads the needed STIX bundles into a temporary directory and
+removes them when generation is complete.
+It always writes detailed HTML, JSON, and Navigator layer artifacts under `output/v{old_version}-v{new_version}`.
+It can also generate `changelog.md` or `index.html` if needed by passing the corresponding flags:
+
+```shell
+attack_changelog --old-version 17.1 --new-version 18.0 \
+  --markdown-file \
+  --html-file
+```
+
 ## Changelog JSON format
 
 The changelog helper script has the option to output a JSON file with detailed differences between ATT&CK releases.
