-## Build
-
-See [CONTRIBUTING.md](CONTRIBUTING.md) for platform-specific dependency setup.
-Use these flags for a development build:
-
-```bash
-cd build
-cmake -DCMAKE_BUILD_TYPE=Debug -DDEBUG_ASSERTIONS_FATAL=ON -DCMAKE_EXPORT_COMPILE_COMMANDS=ON ..
-cmake --build . --parallel $(nproc)
-ctest  # run tests (Google Test)
-```
-
-## Code Style
-
-See [CONTRIBUTING.md](CONTRIBUTING.md) for full conventions. Key points for
-AI-generated code:
-
-- **Formatting**: `.clang-format` (Google base, 4-space indent, 8-space continuation). Only format new/modified code — never mass-reformat.
-- **Separate formatting commits** from logic commits.
-
-### C++ Quick Reference
-
-- Classes: `CamelCase`. Methods: `camelBack()`. Members: `m_prefix`. Pointers: `pPrefix`. Constants: `kPascalCase`. Enums: `enum class CamelCase`.
-- CO/setting keys: `snake_case`.
-- No naked `new`/`delete` — use `std::make_unique`, `std::make_shared`, or `make_parented`.
-- `VERIFY_OR_DEBUG_ASSERT(cond) { recovery; }` for defensive checks.
-- `override` on all virtual overrides; omit redundant `virtual`.
-- `QStringLiteral("...")` for string literals. `tr("...")` for translatable strings.
-- No `goto`. No `Q_UNUSED` (use unnamed params). No C-style enums.
-- `#pragma once`, not include guards.
-- Include order: matching header → system → Qt → library deps → Mixxx local → forward decls. Alphabetical within groups.
-- Wrap new code in `namespace mixxx {}`. Anonymous namespace for file-local helpers in .cpp.
-- Non-const ref out-params: use pointers, not references (legacy convention).
-- Lambdas: use carefully — they get extra review scrutiny for lifetime/control-flow issues.
-
-## Git & PR Workflow
-
-See [CONTRIBUTING.md](CONTRIBUTING.md) for full details. Key rules:
-
-- One branch per feature/bugfix. Every commit must build.
-- Small commits. Imperative commit messages, 72-char wrap, describe what + why.
-- Bug fixes → stable branch (e.g. `2.5`). Features → `main`.
-- Don't rebase without reviewer agreement. Use `--fixup` commits, only squash before merge if requested.
-- Keep PRs focused — no unrelated formatting, config, or refactoring changes mixed in.
-
 ## Key Architecture
 
 - **ControlObject/ControlProxy**: `[Group], key_name` inter-component communication.
