-> For external configuration files, the option names use underscores instead of dashes.
-> Example: `fail_on_severity`
+
+#### `OTHER` in license strings
+
+License data comes from [ClearlyDefined](https://clearlydefined.io) and you may sometimes see licenses displayed with the string `OTHER` in them. ClearlyDefined [defines OTHER](https://docs.clearlydefined.io/docs/curation/curation-guidelines) as:
+
+> This indicates that a human confirmed that there is license information in the file but that the license is not an SPDX-identified license.
+
+`OTHER` is not a valid [SPDX license identifier](https://spdx.org/licenses/), so we convert `OTHER` in a license string into `LicenseRef-clearlydefined-OTHER`, which _is_ valid in SPDX. If you want to add that to the deny or allow list, be sure to add `LicenseRef-clearlydefined-OTHER` to this list, because that is what we'll actually be comparing.
