Contribution to APM
==========================

This section provides details on how to participate/contribute to the APM(Application package manager) project. 

## Build local development environment

This section will guide developers to build APM module locally and help developers to quickly understand and

 code 

The local startup of APM depends on：
```

```
In order to build a local environment, the final startup sequence is [Mecm-Prerequisite](MECM_Prerequisite.md)-> DataBase -> APM
