+#### Construction
+
+Connecting to a standard relayer API compliant url:
+
+```typescript
+const provider = web3.currentProvider;
+const apiUrl = 'https://api.relayer.com/v2';
+const assetBuyer = AssetBuyer.getAssetBuyerForStandardRelayerAPIUrl(provider, apiUrl);
+```
+
+Providing your own orders:
+
+```typescript
+const provider = web3.currentProvider;
+const orders = []; // get these from your own API, a relayer, a friend, from anywhere
+const assetBuyer = AssetBuyer.getAssetBuyerForProvidedOrders(provider, orders);
+```
+
+#### Get a quote
+
+A [BuyQuote](#types-BuyQuote) object contains enough information to display buy information to an end user
+
+```typescript
+const erc20TokenAddress = '0x5fa3c....';
+const amountToBuy = new BigNumber(50000000000000000000);
+const buyQuote = await assetBuyer.getBuyQuoteForERC20TokenAddressAsync(erc20TokenAddress, amountToBuy);
+const quoteInfo = buyQuote.worstCaseQuoteInfo;
+console.log(quoteInfo.ethAmount); // the total amount the user needs to pay to buy the desired amount (including ZRX fees)
+console.log(quoteInfo.feeAmount); // a portion of the total ethAmount above that was used to buy affiliate fees
+console.log(quoteInfo.ethPerAssetPrice); // the rate that this quote provides (e.g. 0.0035ETH / REP)
+```
+
+#### Perform a buy
+
+Pass the [BuyQuote](#types-BuyQuote) object from above back to the assetBuyer in order to initiate the buy transaction
+
+```typescript
+const txHash = await assetBuyer.executeBuyQuoteAsync(buyQuote); // the hash of the transaction submitted to the Ethereum network
+```
