+## @0xproject/contract-wrappers
+
+Smart TS wrappers for 0x smart contracts. The wrappers have simplified interfaces, perform client-side validation on transactions and throw helpful error messages.
+
+### Read the [Documentation](https://0xproject.com/docs/0x.js).
+
+## Installation
+
+**Install**
+
+```bash
+npm install @0xproject/contract-wrappers --save
+```
+
+**Import**
+
+```javascript
+import { ContractWrappers } from '@0xproject/contract-wrappers';
+```
+
+If your project is in [TypeScript](https://www.typescriptlang.org/), add the following to your `tsconfig.json`:
+
+```json
+"compilerOptions": {
+ "typeRoots": ["node_modules/@0xproject/typescript-typings/types", "node_modules/@types"],
+}
+```
+
+## Contributing
+
+We strongly recommend 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
+```
+
+### Build
+
+If this is your **first** time building this package, you must first build **all** packages within the monorepo. This is because packages that depend on other packages located inside this monorepo are symlinked when run from **within** the monorepo. This allows you to make changes across multiple packages without first publishing dependent packages to NPM. To build all packages, run the following from the monorepo root directory:
+
+```bash
+yarn lerna:rebuild
+```
+
+Or continuously rebuild on change:
+
+```bash
+yarn dev
+```
+
+You can also build this specific package by running the following from within its directory:
+
+```bash
+yarn build
+```
+
+or continuously rebuild on change:
+
+```bash
+yarn build:watch
+```
+
+### Clean
+
+```bash
+yarn clean
+```
+
+### Lint
+
+```bash
+yarn lint
+```
+
+### Run Tests
+
+```bash
+yarn test
+```
