The package lacks documentation.

You should improve this tool's documentation guys!

koa-multer just transform the call method to await/async。You can check the documentation expressjs/multer as well.

Please see my comment at #30 (comment) and close this issue. The official Koa organization has forked this repository and released it (with PR's merged) under @koajs/multer. Thank you.
