 *A level is composed of the following elements:*

This factory contract will be deployed only once and registered on Ethernaut.sol by Ethernaut's owner. Players never interact with the factory directly. The factory is in charge of creating level instances for players to use (1 instance per player) and to check these instances to verify if the player has passed the level. Factories should not have state that can be changed by the player.

 - A `level instance` contract named `<Level>.sol`, where `<Level>` is replaced by the name of the level, that is emitted by the factory for each player that requests it. Instances need to be completely decouppled from Ethernaut's architecture. Factories will emit them and verify them. That is, level instances don't know anything about their factories or Ethernaut. An instance's state can be completely demolished by players and even destroyed since they are not really part of the architecture, just a challenge for a player to use at will.
 - A `description file` in [the descriptions directory](./client/src/gamedata/en/descriptions/levels) that the UI presents to the player and describes the level's objectives with some narrative and tips.
 - A `description completion file` also located in [the descriptions directory](./client/src/gamedata/en/descriptions/levels) that the UI presents to the player when the level is passed, further information about the player, historical insights, further explanations or just a congrats message.

 9. Add a completed description markdown file, in this case client/src/gamedata/levels/king_complete.md (make sure gamedata.json points to it). The level will display this as additional info once the level is solved, usually to include historical information related to the level.

+## Foundry
+
+**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.
