@xiaohe27 @yzhang90 and @kheradmand Please review some document changes
@seriousamlqz @kheradmand The users may browse the src/readme.md in the git repository first and then decide how to proceed. If he/she wants to trace all the previous commits and continuously get updated source code, then he/she will checkout the source code via git. However, the users might just be interested in the source code of javamop, but do not care about the past and future of javamop; then it makes sense to remind them to download the stable source release, and then they can play with the source code and build it. Notice that the source code for the release is quite small, much smaller than the project with version control system, and I think this can also become a reason why some users may prefer to download the "zip" or "tar.gz".
