Create new tag for Typescript users

Hey thanks for this project,

However, it seems that with the latest version available on NPM, we still cannot use "descriptions" as the index.d.ts still contains the typo mentioned here: #68

That would be amazing, really. Thanks.

Yup, I have the same problem too. It's kinda annoying to edit index.d.ts file on node module and change the typescript definition from "description" to "descriptions" :/
