 Run `carthage update` to build the framework. By default, Carthage performs checkouts and creates a new directory 'Carthage' in the same location as your Cartfile. Open this directory, go to 'Build' directory, choose iOS or macOS directory, and use the selected directory framework in your Xcode project.

 ### Example usage
 
-**Web3View example:**
+
+##### Send Ether
+
+```swift
+let value: String = "1.0" // In Ether
+let walletAddress = EthereumAddress(wallet.address)! // Your wallet address
+let toAddress = EthereumAddress(toAddressString)!
+let contract = web3.contract(Web3.Utils.coldWalletABI, at: toAddress, abiVersion: 2)!
+let amount = Web3.Utils.parseToBigUInt(value, units: .eth)
+var options = TransactionOptions.defaultOptions
+options.value = amount
+options.from = walletAddress
+options.gasPrice = .automatic
+options.gasLimit = .automatic
+let tx = contract.write(
+    "fallback",
+    parameters: [AnyObject](),
+    extraData: Data(),
+    transactionOptions: options)!
+```
+
+##### Send ERC-20 Token
+
+```swift
+let value: String = "1.0" // In Tokens
+let walletAddress = EthereumAddress(wallet.address)! // Your wallet address
+let toAddress = EthereumAddress(toAddressString)!
+let erc20ContractAddress = EthereumAddress(token.address)!
+let contract = web3.contract(Web3.Utils.erc20ABI, at: erc20ContractAddress, abiVersion: 2)!
+let amount = Web3.Utils.parseToBigUInt(value, units: .eth)
+var options = TransactionOptions.defaultOptions
+options.value = amount
+options.from = walletAddress
+options.gasPrice = .automatic
+options.gasLimit = .automatic
+let method = "transfer"
+let tx = contract.write(
+    method,
+    parameters: [toAddress, amount] as [AnyObject],
+    extraData: Data(),
+    transactionOptions: options)!
+```
+
+##### Write Transaction and call smart contract method
+
+```swift
+let value: String = "0.0" // Any amount of Ether you need to send
+let walletAddress = EthereumAddress(wallet.address)! // Your wallet address
+let contractMethod = "SOMECONTRACTMETHOD" // Contract method you want to write
+let contractABI = "..." // Contract ABI
+let contractAddress = EthereumAddress(contractAddressString)!
+let abiVersion = 2 // Contract ABI version
+let parameters: [AnyObject] = [...]() // Parameters for contract method
+let extraData: Data = Data() // Extra data for contract method
+let contract = web3.contract(contractABI, at: contractAddress, abiVersion: abiVersion)!
+let amount = Web3.Utils.parseToBigUInt(value, units: .eth)
+var options = TransactionOptions.defaultOptions
+options.value = amount
+options.from = walletAddress
+options.gasPrice = .automatic
+options.gasLimit = .automatic
+let tx = contract.write(
+    contractMethod,
+    parameters: parameters,
+    extraData: extraData,
+    transactionOptions: options)!
