I had started on this and totally didn't read your update this morning! 🤣 I confirmed on my personal machine that SwiftLint indeed needs to be installed before it'll work with our project so I'm glad this is in place. Didn't know about the pod install way though.

Left a comment about the pod installation script, but otherwise looks good. Glad you have this markdown linter. I much prefer that style for bulleted lists.
