Description

Added solidity course "* Solidity Smart Contract Development - Patrick Collins, Austin Griffith”

Why is this valuable (or not)?

How do we know it's really free?

For book lists, is it a book? For course lists, is it a course? etc.

please remove the package-lock file (use a .gitignore file)

[eshellman]

hmm the linter doesn't like adding that to .gitignore instead, just remove the file from your repo; we'll figure out how to manage changes to gitignore separately

[anand-242003]

I've removed package-lock.json from the repository as the linter didn't approve of adding it to .gitignore. Could you please guide me on the next steps or any further changes needed?

[eshellman]

maybe you need to push your commits

[anand-242003]

I've made the changes and pushed them again. Let me know if there's anything else I should adjust .

[eshellman]

I see the problem. you ned to undo your change to .gitignore
