Hello @aungkhanthtoo! I took a look at your repository, and it looks like you've been following the directions. I'm going to pass this on to our engineering team to see if they can figure out what's going on. In the meantime, do you mind trying to re-open [issue #2](https://github.com/aungkhanthtoo/github-slideshow/issues/2), and create one more branch while the issue is open? Let me know how it goes!
@robertogcalle Thank you for posting that here. I'll pass this along as well, and hopefully something will be sorted out soon.
