1. Truffle distributes HD wallet through npm. Use the regular install command to get it:

npm install truffle-hdwallet-provider

2. This provider supports non-Truffle projects. Use it wherever a web3 provider is needed. Import the package using the require statement:

var HDWalletProvider = require("truffle-hdwallet-provider");

3. Use the mnemonic phrase and an Ethereum endpoint to create a provider:

// 12 word mneminic to create randomnessvar mnemonic = "cat oreo water ...";var provider = new HDWalletProvider(mnemonic, "http://localhost:8545");

var addressIndex = 7;var provider = new HDWalletProvider(mnemonic, ...
