why sources uploaded to github as zipped archive instead of properly added the whole file structure? Are you going to do standard development there or this is just a fake account and fake github? You need to explain this.
Files are loaded as other coins do, in the format required by mostly of the pools and exchanges. It has not any secret and everyone can download it and compile the wallets by himself or change the file format as he wish. Please show me the sample of a github account as you like, so i can see what are the differences.
Do you plan to have a normal development there? If yes, how would you checkout and commit from the zip? How would anyone see what are the changes between 2 commits if you put a zip there? Having zip is only possible if your main repository is somewhere else, but it is not truly open source .
