-## Foundry
+# Foundry Fund Me
 
-**Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.**
-
-Foundry consists of:
-
--   **Forge**: Ethereum testing framework (like Truffle, Hardhat and DappTools).
--   **Cast**: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
--   **Anvil**: Local Ethereum node, akin to Ganache, Hardhat Network.
--   **Chisel**: Fast, utilitarian, and verbose solidity REPL.
