Deplpoyment to Github pages should stay. There is no reason to move away from gh-pages.

[mariobehling]

You can deploy master to gh-pages and development to heroku for testing, but keep gh-pages, please.

[simsausaurabh]

@mariobehling Ok, sorry for that. I am keeping master branch deployment to gh-pages. We need to deploy development on heroku for testing. gh-pages should not have both of these deployments(from master and development). So for creating deployment of development branch to heroku for testing, it requires access to repo. Could you please create a repo on heroku for the same?

[simsausaurabh]

@hemantjadon please review.

@mariobehling please review.

[praveenojha33]

@simsausaurabh As this PR is for development branch, I think deploy.sh should be updated to deploy on heroku. Earlier in this PR you removed deploy.sh from .travis.yml , but why you included it again?

LGTM 👍
