What is starknet? How it all works?
https://starkware.co/starknet/
User Guide . 1.Wallet.
You need a wallet. If you are user of metamask, that's not all. You need to download Argent X(chrome extension) or Bravos(mobile wallet or extension). Download the extension. Secure your passphrase and make a password. If you forget your password, reinstall the extension and import your wallet. If you loose your passphrase, it's finished.
Till now none of these wallets (Starknet based) have social recovery option.
2. Bridging funds. At present I can think of two good solutions. Orbiter finance and starknet official bridge. That starknet bridge works only from eth mainnet to straknet. However orbiter bridge works from other EVM chains also. Hence it consumes less fee.

3.Interact with dapps. Now you have funds in your wallet. Do simple things like swap, provide liquidity. Not much to do here. Sometimes it fees starknet is real L2 Or may be they are in beta phase. Transaction will get longer time to confirm and may even get cancelled. If you provide large amount of liquidity there may be huge price impact. You can also buy nfts for as low as $1. dapps prominent. 10kswap, myswap, aspect, mintsquare. Also bravos wallet as in-wallet swap feature. Use it. Don't try to do too many transaction as it will go invain. Do 1 txn and give it some time to confirm. It may take even 10minutes.
You can proceed to NFT web pages directly from braavos itself.
