+#### Enabling code coverage checks on your fork
+
+If you simply fork the repo and then create a PR sourced from it, your PR will fail its test coverage check. This is because the 0x CircleCI configuration sets the `COVERALLS_REPO_TOKEN` environment variable to the token for 0xProject/0x-monorepo, but when running the check against your fork the token needs to match the repo that is your fork, rather than the 0x repo.
+
+To facilitate this check, after creating your fork, but before creating the branch for your PR, do the following:
+
+1.  Log in to [coveralls.io](https://coveralls.io/), go to Add Repos, and enable your fork. Then go to the settings for that repo, and copy the Repo Token identifier.
+2.  Log in to [CircleCI](https://circleci.com/login), go to Add Projects, click the Set Up Project button corresponding to your fork, and then click Start Building. (Aside from step 3 below, no actual set up is needed, since it will use the `.circleci/config.yml` file in 0x-monorepo, so you can ignore all of the instruction/explanation given on the page with the Start Building button.)
+3.  In CircleCI, configure your project to add an Environment Variable, with name `COVERALLS_REPO_TOKEN`, and for the value paste in the Repo Token you copied in step 1.
+
+Now, when you push to your branch, CircleCI will automatically run all of the checks in your own instance, and the coverage check will work since it has the proper Repo Token, and the PR will magically refer to your own checks rather than running them in the 0x CircleCI instance.
+
 ### Styleguide
 
 We use [TSLint](https://palantir.github.io/tslint/) with [custom configs](https://github.com/0xProject/0x-monorepo/tree/development/packages/tslint-config) to keep our code style consistent.

 ### Build
 
-Build all packages. You need to do this before working on any given package. Although these packages
-as independent, when run from within the monorepo, they are internally symlinked, to make development
-easier. You can change several packages and run the changes without publishing them first to NPM. When
-running `rebuild`, Lerna will figure out the dependency order of all the packages, and build them in
-this order.
+To build all packages:
 
 ```bash
-yarn lerna:rebuild
+yarn build
 ```
 
-Or continuously rebuild on change:
+To build a specific package:
 
 ```bash
-yarn dev
+PKG=@0x/web3-wrapper yarn build
+```
+
+### Watch
+
+To re-build all packages on change:
+
+```bash
+yarn watch
+```
+
+To watch a specific package and all it's dependent packages:
+
+```bash
+PKG=[NPM_PACKAGE_NAME] yarn watch
+
+e.g
+PKG=@0x/web3-wrapper yarn watch
+```
+
+### Clean
+
+Clean all packages:
+
+```bash
+yarn clean
+```
+
+Clean a specific package
+
+```bash
+PKG=0x.js yarn clean
+```
+
+### Rebuild
+
+To re-build (clean & build) all packages:
+
+```bash
+yarn rebuild
+```
+
+To re-build (clean & build) a specific package & it's deps:
+
+```bash
+PKG=0x.js yarn rebuild
 ```
 
 ### Lint
 
-Lint all packages
+Lint all packages:
 
 ```bash
-yarn lerna:run lint
+yarn lint
+```
+
+Lint a specific package:
+
+```bash
+PKG=0x.js yarn lint
 ```
 
 ### Run Tests
 
+Run all tests:
+
 ```bash
-yarn lerna:test
+yarn test
+```
+
+Run a specific package's test:
+
+```bash
+PKG=@0x/web3-wrapper yarn test
 ```

+## @0x/abi-gen-wrappers
+
+Low-level 0x smart contract wrappers generated using @0x/abi-gen. These
+low-level wrappers are imported by other packages in the 0x monorepo and
+application developers are not expected to import this package directly.
+
+You may also be interested in the
+[@0x/contract-wrappers](../contract-wrappers/README.md) package which
+includes some higher-level features.
+
+## Installation
+
+```bash
+yarn add @0x/abi-gen-wrappers
+```
+
+**Import**
+
+```typescript
+import * as wrappers from '@0x/abi-gen-wrappers';
+```
+
+or
+
+```javascript
+var wrappers = require('@0x/abi-gen-wrappers');
+```
+
+## Contributing
+
+We welcome improvements and fixes from the wider community! 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:

+yarn install
+```
+
+### Build
+
+To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:

+```
+
+### Clean
+
+```bash
+yarn clean
+```
+
+### Lint
+
+```bash
+yarn lint
+```
+
+### Run Tests

 It's heavily inspired by [Geth abigen](https://github.com/ethereum/go-ethereum/wiki/Native-DApps:-Go-bindings-to-Ethereum-contracts) but takes a different approach.
 You can write your custom handlebars templates which will allow you to seamlessly integrate the generated code into your existing codebase with existing conventions.

 We use [handlebars](http://handlebarsjs.com/) template engine under the hood.
 You need to have a master template called `contract.mustache`. it will be used to generate each contract wrapper. Although - you don't need and probably shouldn't write all your logic in a single template file. You can write [partial templates](http://handlebarsjs.com/partials.html) and as long as they are within a partials folder - they will be registered and available.

 ### 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:
