Is there a way to specify content type or document processor for files with no extension?

[glopesdev]

I have been trying to avoid changing the extension of the LICENSE file in one of our projects to LICENSE.md just to have it render correctly by DocFX.

No changes would be required to the actual file contents if it was possible to specify that the content type of this specific file is markdown.

Is there a simple way to do this from docfx.json? I've looked at fileMetadata and documentation on the schema-driven processor, but I always get confused by how the workflow is supposed to go for simple cases like this.
