-Unlike other programming languages, creating a Huff contract that returns "Hello, world!" is quite advanced! To keep things simple we are going to learn how to create a Huff contract that adds two numbers (then we will dive into "Hello, world!").

 The contract ABI specification dictates that contract calls will select which function they want to call by prepending a 4 byte (function selector) to their calls. The 4 bytes are sliced from the start of the keccak of the function's abi definition. For example, `addTwo(uint256,uint256)`'s function selector will become `0x0f52d66e` (You can confirm this by using a command line tool such as [`cast`](https://book.getfoundry.sh/cast/)'s `sig` command, or online sites such as [keccak256 online](https://emn178.github.io/online-tools/keccak_256.html)). If you are curious as to what these look like you can find a registry of common 4byte function selectors in the [4 byte directory](https://www.4byte.directory/).
 
-Calculating the function selector each time can be tedious. To make life easy, huff has an included builtin `__FUNC_SIG()`. If a function interface is declared within the file's current scope, it's function selector will be calculated and inlined for you. You can view more information about huff's builtin functions [here](/get-started/huff-by-example/#func-sig-func-def-string).
