option	description	optional	default
deployedDir	path to generated deployed directory (relative to Hardhat root)	true	scripts/deployed
ignoreContracts	which contracts wants to ignore	true	[]

example:

deployed: {
    deployedDir: "scripts/deployed",
    ignoreContracts: ["MockERC20", "Foo"],
}

4. The scripts/deployed directory's structure and how to use generated functions

when you execute npx hardhat deployed init [--netwrok <network>] task, it will generate default scripts/deployed directory(if you not set a different deployedDir value in hardhat.config.ts config file).

following is a scripts/deployed directory example:

so, in your deploy scripts, you can use get<Foo>Contract(): string function to get contract's address; and use save<Foo>Contract(addr: string) function to save contract's address.
