[devnet0x]

Done, please your review @dalmasonto thanks

[dalmasonto]

Hello @devnet0x seems it didn't work, there are two files having some style problems, hope you did run npm run format

[devnet0x]

Sorry @dalmasonto , please check again

[dalmasonto]

Still you have same error, that is code style formatting error, that is why "all checks have failed" from above. I have made a quick fork of your repo and created a PR for the same devnet0x#1, I have formatted the docs their, just check it out, if your work is all there you can merge and see whether the above checks pass that is the prettier format checks

[devnet0x]

done

Thanks, @devnet0x! Your updates are clear and I'm ready to merge them. Please address the conflict in the foundry forge chapter, as your well-formatted PR clashes with its previous state which was badly formatted.

Appreciate the review, @dalmasonto!

[devnet0x]

updated and now all check passed, please could you check @dalmasonto @omarespejel ?
