+# Get started - Use DX in your project
+Add it to your project:
+
+```bash
+# Install the dependencies
+yarn add truffle-contract @gnosis.pm/dx-contracts --save # or npm install @gnosis.pm/dx-contracts --save
+```
+
+You will find the compiled truffle contracts in the `build/contracts` folder,
+these contract abstractions will also contain the addresses for the DX for 
+**mainnet** and the **testnets**.
+
+For example:
+```js
+const contract = require('truffle-contract')
+
+// Create the truffle contracts
+const DutchExchangeProxy = contract(require('@gnosis.pm/dx-contracts/build/contracts/DutchExchangeProxy'))
+const DutchExchange = contract(require('@gnosis.pm/dx-contracts/build/contracts/DutchExchange'))
+
+// Setup your provider
+// provider = ...
+DutchExchange.setProvider(provider)
+DutchExchangeProxy.setProvider(provider)
+
+// Get the contract instance
+DutchExchangeProxy.deployed(async proxy => {
+  const dx = DutchExchange.at(proxy.address)
+
+  // Use any of the dx methods
+  const token1 = '0x123456'
+  const token1 = '0x654321'
+  const auctionIndex = await dx.getAuctionIndex.call(token1, token2)
+  console.log(auctionIndex)
+})
+```
