# This is NOT the Next.js you know This version has breaking changes — APIs, conventions, and file structure may all differ from your training data. Read the relevant guide in `node_modules/next/dist/docs/` before writing any code. Heed deprecation notices. # Codex workflow Before making repository changes, Codex should work from a dedicated branch in the Codex worktree. Prefer a `codex/...` branch name when Git refs allow it; if an existing ref blocks that namespace, use a `codex-...` branch name instead.
