I was trying to use jerryscript on esp8266. But the way showing in ["/target/esp8266"](https://github.com/jerryscript-project/jerryscript/blob/master/targets/esp8266/readme.md) is different from ["getting start page"](https://github.com/jerryscript-project/jerryscript/blob/master/docs/00.GETTING-STARTED.md). And I don't know how to build an [API-Example-8](https://github.com/jerryscript-project/jerryscript/blob/master/docs/03.API-EXAMPLE.md#example-8-simple-javascript-shell) for esp8266. Is there anyway to build throw tools/build.py. And can I use AT-Comand after flash jerryscritp into esp8266?
