Travis CI is a continuous integration server for open-source projects, integrated with GitHub - to use it you have to login with your GitHub account, next in https://travis-ci.org/profile you need to enable proper repository (by pressing on/off button) and that's all - it will start building of openmw everytime something will be merged into master or next branch.
