-## ethers-typescript-typings
-
-There currently isn't an official [Ethers][ethers]
-type definition included in the [DefinitelyTyped][definitelytyped] project.
-Until that happens, we will continue to improve our own type definition.
-If it get's close to comprehensive, we'll add it to [DefinitelyTyped][definitelytyped].
