+## Uniswap V4 Liquidity Pools
+Uniswap V4 introduces hooks and a new pool manager architecture. The `UniswapV4Pool` class provides access to V4 pools with support for the new features.

 ## Forking With Anvil
 The `AnvilFork` class is used to launch a fork with `anvil` from the [Foundry](https://github.com/foundry-rs/foundry) toolkit. The object provides a `w3` attribute, connected to an IPC socket, which can be used to communicate with the fork like a typical RPC.
