How to use Starknet with Ledger?

Could you possibly explain how one might utilize Starknet in conjunction with a Ledger device? I'm quite interested in understanding the integration process and what steps are involved in setting it up. Would it require any specific software or apps to be installed? And once integrated, how would the Ledger enhance the security of Starknet transactions? I'm also curious about any potential limitations or challenges that might arise during this process. Could you please elaborate on these points?
