 ## Geth
 `Geth` is responsible for interacting with Ethereum network. Geth interacts with network via JSONRPC. You can see the list of JSONRPC requests [here](Documentation/JSONRPC.md).
+To create `Configuration` struct for `Geth`, you need 
+- url for Ethereum node. you can get one at [infura.io](https://infura.io)
+- Etherscan API key. you can get one at [Etherscan](https://etherscan.io)

+### Get Transactions
+To get the list of transactions related to the specified address, `Geth` uses Etherscan API.
+
+```swift
+geth.getTransactions(address: address) { result in
+    // Do something            
+}
+```

 ### Send Ether
 You need to create `RawTransaction` with 
 - value (how much ether/wei you want to send)
