-## 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].
-
-[ethers]: https://github.com/ethers-io/ethers.js
-[definitelytyped]: https://github.com/DefinitelyTyped/DefinitelyTyped
-
-## Installation
-
-```bash
-yarn add -D ethers-typescript-typings
-```
-
-## Usage
-
-Add the following line within an `include` section of your `tsconfig.json`
-
-```json
-"./node_modules/ethers-typescript-typings/index.d.ts"
-```
-
-## Contributing
-
-We strongly encourage that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
-
-Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
-
-### Install Dependencies
-
-If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them:
-
-```bash
-yarn config set workspaces-experimental true
-```
-
-Then install dependencies
-
-```bash
-yarn install
-```
-
-### Lint
-
-```bash

-## chai-typescript-typings

-Fork of type definitions for chai that includes changes made by dirty-chai
+Type repository for external packages used by 0x. This is like our small version of [DefinitelyTyped](https://github.com/DefinitelyTyped/DefinitelyTyped)
 
 ## Installation
 
 ```bash
-yarn add -D chai-typescript-typings
+yarn add -D @0xproject/typescript-typings
 ```
 
 ## Usage
 
-Add the following line within an `include` section of your `tsconfig.json`
+Add the following line within an `compilerOptions` section of your `tsconfig.json`
 
 ```json
-"./node_modules/chai-typescript-typings/index.d.ts"
+"typeRoots": ["node_modules/@0xproject/typescript-typings/types", "node_modules/@types"]
 ```
 
+This will allow the TS compiler to first look into that repo and then fallback to DT types.

-## web3-typescript-typings
-
-There currently isn't an official [Web3][web3]
-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].
