-## Contracts
+## AssetProxy
 
-Smart contracts that implement the 0x protocol. Addresses of the deployed contracts can be found in the 0x [wiki](https://0xproject.com/wiki#Deployed-Addresses) or the [CHANGELOG](./CHANGELOG.json) of this package.
+This package contains the implementations of all of the [`AssetProxy`](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#assetproxy) contracts available within the 0x protocol. These contracts are responsible for decoding the `assetData` sent to them and performing the actual transfer of assets. Addresses of the deployed contracts can be found in the 0x [wiki](https://0xproject.com/wiki#Deployed-Addresses) or the [DEPLOYS](./DEPLOYS.json) file within this package.
 
-## Usage
+## Installation
 
-Contracts that make up and interact with version 2.0.0 of the protocol can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
+**Install**
 
--   [protocol](./contracts/protocol)
-    -   This directory contains the contracts that make up version 2.0.0. A full specification can be found [here](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md).
--   [test](./contracts/test)
-    -   This directory contains mocks and other contracts that are used solely for testing contracts within the other directories.

-Smart contract interfaces of the 0x protocol.
+This package contains implementations of various [ERC20](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-20.md) tokens, including WETH (Wrapped Ether) and ZRX. Addresses of the deployed contracts can be found in the 0x [wiki](https://0xproject.com/wiki#Deployed-Addresses) or the [DEPLOYS](./DEPLOYS.json) file within this package.
 
-## Usage
+## Installation
 
-Contracts that make up and interact with version 2.0.0 of the protocol can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:

-## Contracts libs
+## ERC721 Tokens
 
-Smart contracts libs used in the 0x protocol.
+This package contains implementations of various [ERC721](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-721.md) tokens. Addresses of the deployed contracts can be found in the 0x [wiki](https://0xproject.com/wiki#Deployed-Addresses) or the [DEPLOYS](./DEPLOYS.json) file within this package.
 
-## Usage
+## Installation
 
-Contracts can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
+**Install**
 
--   [libs](./contracts/protocol)
-    -   This directory contains the libs.
--   [test](./contracts/test)
-    -   This directory contains mocks and other contracts that are used solely for testing contracts within the other directories.
+```bash
+npm install @0x/contracts-erc721 --save
+```
+
+## Bug bounty
+
+A bug bounty for the 2.0.0 contracts is ongoing! Instructions can be found [here](https://0xproject.com/wiki#Bug-Bounty).

-## Token contracts
+## Exchange Forwarder
 
-Token smart contracts that are used in the 0x protocol. Addresses of the deployed contracts can be found in the 0x [wiki](https://0xproject.com/wiki#Deployed-Addresses) or the [CHANGELOG](./CHANGELOG.json) of this package.
+This package contains the implementation of the [`Forwarder`](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/forwarder-specification.md) contract. This contract is intended to improve the UX of interacting with the 0x [`Exchange`](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#exchange) contract by abstracting user approvals, converting ETH to WETH, and paying fees. Addresses of the deployed contracts can be found in the 0x [wiki](https://0xproject.com/wiki#Deployed-Addresses) or the [DEPLOYS](./DEPLOYS.json) file within this package.
 
-## Usage
+## Installation
 
-Token contracts that make up and interact with version 2.0.0 of the protocol can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
+**Install**
 
--   [tokens](./contracts/tokens)
-    -   This directory contains implementations of different tokens and token standards, including [wETH](https://weth.io/), ZRX, [ERC20](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-20.md), and [ERC721](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-721.md).
--   [test](./contracts/test)
-    -   This directory contains mocks and other contracts that are used solely for testing contracts within the other directories.

-## Contract examples
+## Exchange Libraries
 
-Example smart contracts that interact with 0x protocol.
+This package contains the implementations of various libraries and utilities used within the [`Exchange`](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#exchange) contract. These libraries may be useful when creating external contracts that interact with the `Exchange` contract. Addresses of the deployed contracts can be found in the 0x [wiki](https://0xproject.com/wiki#Deployed-Addresses) or the [DEPLOYS](./DEPLOYS.json) file within this package.
 
-## Usage
+## Installation
 
-Contracts can be found in the [contracts](./contracts) directory.
-This package contains example implementations of contracts that interact with the protocol but are _not_ intended for use in production. Examples include [filter](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#filter-contracts) contracts, a [Wallet](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#wallet) contract, and a [Validator](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#validator) contract, among others.

+## Exchange
+
+This package contains the implementation of the [`Exchange`](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#exchange). This contract is responsible for settling trades and is typically the entry point for all transactions that interact with the 0x protocol. Lightweight examples of how external contracts can interct with the `Exchange` contract can be found in the [examples](./contracts/examples) directory. Addresses of the deployed contracts can be found in the 0x [wiki](https://0xproject.com/wiki#Deployed-Addresses) or the [DEPLOYS](./DEPLOYS.json) file within this package.
+
+## Installation
+
+**Install**
+
+```bash
+npm install @0x/contracts-exchange --save
+```
+
+## Bug bounty
+
+A bug bounty for the 2.0.0 contracts is ongoing! Instructions can be found [here](https://0xproject.com/wiki#Bug-Bounty).
+
+## 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.
+
+For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein.

-## Contract extensions
+## Extensions
 
-Smart contracts that implement extensions for the 0x protocol.
+This package implements various extensions to the 0x protocol. Extension contracts can add various rules around how orders are settled while still getting the interoperability and security benefits of using the underlying 0x protocol contracts. Addresses of the deployed contracts can be found in the 0x [wiki](https://0xproject.com/wiki#Deployed-Addresses) or the [DEPLOYS](./DEPLOYS.json) file within this package.
 
-## Usage
+## Installation
 
-Contract extensions of the protocol can be found in the [contracts](./contracts) directory. This directory contains contracts that interact with the 2.0.0 contracts and will be used in production, such as the [Forwarder](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/forwarder-specification.md) contract.
+**Install**
+
+```bash
+npm install @0x/contracts-extensions --save
+```

-## MultisSig Contracts
+## MultiSignature Contracts
 
-MultiSig smart contracts
+This package contains various types of multisignature wallet contracts, including the [`AssetProxyOwner`](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#assetproxyowner) contract that is responsible for upgrading the 0x protocol smart contracts. Addresses of the deployed contracts can be found in the 0x [wiki](https://0xproject.com/wiki#Deployed-Addresses) or the [DEPLOYS](./DEPLOYS.json) file within this package.
 
-## Usage
+## Installation
 
-Contracts can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
+**Install**
 
--   [multisig](./contracts/multisig)
-    -   This directory contains the [Gnosis MultiSigWallet](https://github.com/gnosis/MultiSigWallet) and a custom extension that adds a timelock to transactions within the MultiSigWallet.
--   [test](./contracts/test)
-    -   This directory contains mocks and other contracts that are used solely for testing contracts within the other directories.
+```bash
+npm install @0x/contracts-multisig --save
+```

 ## Contracts utils
 
-Smart contracts utils used in the 0x protocol.
+This package contains smart contract utilities and libraries that are used throughout the entire codebase of smart contracts. These contracts are all generic and may helpful to use outside of the context of 0x protocol.
 
-## Usage
+## Installation
 
-Contracts can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
+**Install**
