When you are at GitHub, every subdirectory of this repo is a separate sample project that you can use if you have a similar project.

But when you are viewing this right now as web page in xdvrx1.github.io domain, you need to click View on GitHub to download the source codes.

Thanks!

1. Fork the repo!
2. Then, made changes and create a pull request.
3. If not fork, just please star this. Thanks!
