 They provide a way for users to add, remove and update this orderbook through an API, GUI or both. In doing so, relayers help traders discover counter-parties and ferry cryptographically signed orders between them. Once two parties agree on the terms of an order, the order is settled directly on the Ethereum blockchain via the 0x protocol smart contracts.

 ## Ethereum Intro
 
 Welcome to the exciting world of building applications on the [Ethereum Blockchain](https://www.ethereum.org/). With Ethereum you can deploy applications or "Smart Contracts" that perform operations and persist state using a decentralized network of computers. Ethereum is often described as a platform for programming digital money. A transaction executes and is confirmed and verified by hundreds of different machines (nodes) distributed around the world. If you want to understand the how blockchains fundamentally work checkout [this visual explanation](https://anders.com/blockchain/).

 ## Sol-coverage
 
 Sol-coverage uses transaction traces in order to figure out which lines of Solidity source code have been covered by your tests. In order for it to gather these traces, you must add the `CoverageSubprovider` to the [ProviderEngine](https://github.com/MetaMask/provider-engine) instance you use when running your Solidity tests. If you're unfamiliar with `ProviderEngine`, please read the [Web3 Provider explained](https://0x.org/wiki#Web3-Provider-Explained) wiki article.
