 ## Requirements
 ```
 Node >= 7.6
+Web3 <= 1.0.0-beta.37
 ```
 
 ## General Usage
 
 You can use this provider wherever a Web3 provider is needed, not just in Truffle. For Truffle-specific usage, see next section.
 
 ```javascript
-var HDWalletProvider = require("truffle-hdwallet-provider");
-var mnemonic = "mountains supernatural bird..."; // 12 word mnemonic
-var provider = new HDWalletProvider(mnemonic, "http://localhost:8545");
+const HDWalletProvider = require("truffle-hdwallet-provider");
+const Web3 = require("web3");
+const mnemonic = "mountains supernatural bird..."; // 12 word mnemonic
+let provider = new HDWalletProvider(mnemonic, "http://localhost:8545");
 
 // Or, alternatively pass in a zero-based address index.
-var provider = new HDWalletProvider(mnemonic, "http://localhost:8545", 5);
+provider = new HDWalletProvider(mnemonic, "http://localhost:8545", 5);
 
 // Or, use your own hierarchical derivation path
-var provider = new HDWalletProvider(mnemonic, "http://localhost:8545", 5, 1, "m/44'/137'/0'/0/");
+provider = new HDWalletProvider(mnemonic, "http://localhost:8545", 5, 1, "m/44'/137'/0'/0/");
 
 
 // HDWalletProvider is compatible with Web3. Use it at Web3 constructor, just like any other Web3 Provider
-const web3 = new Web3(provider); 
+const web3 = new Web3(provider);
 
 // Or, if web3 is alreay initialized, you can call the 'setProvider' on web3, web3.eth, web3.shh and/or web3.bzz
 web3.setProvider(provider)

 Instead of a mnemonic, you can alternatively provide a private key or array of private keys as the first parameter. When providing an array, `address_index` and `num_addresses` are fully supported.

 **NOTE: This is just an example. NEVER hard code production/mainnet private keys in your code or commit them to git. They should always be loaded from environment variables or a secure secret management system.**
