 The TileLang backend requires the `tilelang` Python package.
 
-## Adding a New Operator
-
-1. Create `ops/<name>/nvidia/<name>_cuda.h` with the C API (4 functions: create, workspace, execute, destroy).
-2. Create `ops/<name>/nvidia/<name>_cuda.cu` with the CUDA implementation.
-3. Create `python/operator_runtime/ops/<name>.py` using `operator_runtime._internal.bind_*` functions.
-4. Create `tests/cases/<name>.py` with `correctness_cases()`, `api_error_cases()`, and `benchmark_cases()`.
-5. Create `tests/ops/test_<name>.py` and `tests/bench/<name>.py`.
-6. Re-run `cmake ..` in the build directory (the glob will pick up the new `.cu` file).
-7. Register the public API in `python/operator_runtime/__init__.py`.
-
-No YAML, no code generation, no registration step.

 TileLang 后端需要安装 `tilelang` Python 包。
 
-## 如何新增算子
-
-1. 创建 `ops/<name>/nvidia/<name>_cuda.h`，提供 4 个 C API：create、workspace、execute、destroy。
-2. 创建 `ops/<name>/nvidia/<name>_cuda.cu`，实现 CUDA 逻辑。
-3. 创建 `python/operator_runtime/ops/<name>.py`，使用 `operator_runtime._internal.bind_*` 绑定。
-4. 创建 `tests/cases/<name>.py`，提供 `correctness_cases()`、`api_error_cases()` 和 `benchmark_cases()`。
-5. 创建 `tests/ops/test_<name>.py` 和 `tests/bench/<name>.py`。
-6. 在构建目录里重新执行 `cmake ..`，因为 glob 会自动拾取新的 `.cu` 文件。
-7. 在 `python/operator_runtime/__init__.py` 中导出公共 API。
-
-这里没有 YAML、没有代码生成、也没有额外的注册步骤。
