@nud3l it would be great if you could review the contract functions before I proceed to write the detailed documents. Just want to check if u are expecting any additional functionalities.

@nakul1010 code LGTM, would be great to get the docs updated next. Thank you!

@nud3l
I think the HelloBitcoin should be in another repo here are the issues I faced during building/deployment

• The Bob repo already contains docs, multiple contracts and much more. As a smart contract, i would rather prefer an empty starter kit with only a hello world contract.
• Keeping the Hello world in Bob doesn't exactly help new users,
  • no installation of bob-collective/bob is needed currently as HelloWorld in the same repo
  • multiple deployment scripts present
  • smart contract user continuously needs to maintain/upgrade a fork of bob-collective/bob
  • solidity version clashes between libraries if i create a new project with foundry
• Currently coming to Bob as a developer feels like an info dump with lots of contracts and unnecessary code that is related to the main website.
• As a dev, i would rather prefer a separate repo, from which I get the helloworld code, and basic installation setup done ie (bob-collective/bitcoin-spv/open Zepplin/account abstraction libraries installed with compatible solidity versions, scripts, and readme), and can carry forward my idea on building top of bob.

It will be a hassle maintaining 2 repos, but if we release tags it can be much simpler.

Excellent points, let's move this to a dedicated repo then @nakul1010 !

Cool will keep this PR open, as it should just handle the documentation part.

Some minor comments, but overall, LGTM!
