# Develop and Improve
Build System
We use Open Build Service(OBS) as our build system. And currently we are testing our new build system.
Source Code
We use GitHub as our source code repository and continuous integration (CI) platform.
Test Server
We have a VM with eweOS installed (really unstable!) and run some useful web programs for packagers.
User Repository (Soon™)
We'll have eweOS User Repository (EUR), a community-driven repository.
