@sirisayshello thankyou for your contribution to Hyperledger Cacti.
I have some review comments on this one

1. Can you please comment on the task docs(ledger-browser): add links to documentation #3550 with something like I want to work on this, so that we can assign you the task. This helps us in avoiding duplications of the efforts spent on its completion.
2. Can you update the commit message with what you wrote as the pr description as well? (All you have to do is amend the commit message with the exact copy paste of your pr description, without the Pull Request Requirements.... paragraph). This helps us with descriptive commit messages and a parity with the PR associated with them.
