📝 Walkthrough

Walkthrough

The README.md has been substantially refactored from a detailed "Minimal C++23 2D engine foundation" specification into a more concise, higher-level project description. The enumerated features list (player movement, editor camera controls, grid utilities, custom ImGui helpers, YAML persistence) was condensed into fewer capability categories. A new "Controls" section documenting key bindings was introduced, the "Roadmap" section was restructured to outline near and long-term goals, and build instructions were significantly simplified by removing vcpkg and CLion configuration details. The "Tech" dependency list was also condensed, resulting in a net reduction of 121 lines.

Right then, newcomer—nice to see you reviewing docs. Here's the thing with README rewrites: they're low-risk but you'll want to scan for consistency in tone and accuracy. Check that the Controls section matches what the code actually does, and make sure the Roadmap doesn't contradict what's currently implemented. Documentation's often neglected, so when someone actually bothers to tidy it up, that's worth a proper read-through. Solid work spotting this one.
