# How to contribute to the runtime-core of JS framework
## 1. Modify code
## 2. Compile the framework itself
> npm install
> npm run build
you will get the **framework.min.js** output under `runtime-core/build` folder
## 3. Prepare the snapshot tool
run `ace_lite_jsfwk/tools/snapshot/jerry-bin/build_jerry.sh`, the `jerry-snapshot` tool will be generated into `ace_lite_jsfwk/tools/snapshot/jerry-bin/linux/`.
## 4. Generate framework.min.bc
> cd packages/runtime-core/build/
> ./../../../tools/snapshot/jerry_bin/linux/jerry-snapshot generate -o framework.min.bc ./framework.min.js
## 5. Update the JS and snapshot array in C++ code
> cd tools/snapshot/
> python framework2char.py
## 6. add changed file to git
> git add src/core/base/framework_min_js.h
> git add src/core/base/framework_min_bc.h
