+# 🔧 Lumen_cli
+A Python CLI tool for building and testing PyTorch-based components, using a YAML configuration file for structured, repeatable workflows.
+
+
+## Features
+- **Build**
+    - external projects (e.g. vLLM)
+
+## 📦 Installation
+at the root of the pytorch repo
+```bash
+pip install -e .ci/lumen_cli
+```
+
+## Run the cli tool
+The cli tool must be used at root of pytorch repo, as example to run build external vllm:
+```bash
+python -m cli.run build external vllm
+```
+this will run the build steps with default behaviour for vllm project.
+
+to see help messages, run
+```bash
+python3 -m cli.run --help
+```
+
+## Add customized external build logics
+To add a new external build, for instance, add a new external build logics:
+1. create the build function in cli/lib folder
+2. register your target and the main build function at  EXTERNAL_BUILD_TARGET_DISPATCH in `cli/build_cli/register_build.py`
+3. [optional] create your ci config file in .github/ci_configs/${EXTERNAL_PACKAGE_NAME}.yaml
