Worked on the metal-stack/mini-lab repository to deliver a focused documentation update that improved the accuracy of firewall provisioning instructions. Addressed a key onboarding issue by updating the README, replacing the outdated 'machine create' command with the correct 'firewall create' command, and clarifying the network placeholder to better reflect the current CLI workflow. This change, implemented using Markdown and leveraging strong documentation skills, ensures that users can provision firewall resources directly within the mini-lab environment. The update reduces confusion for new users and aligns the documentation with live system behavior, supporting a smoother setup process and minimizing support requests.
