@sudiptog81 thanks for the contribution!

The current issue template in this pull request looks like a bug report template, do you think you can also add a feature request template, as not all the issues are bug related?

I think we can do it by putting them in the folder:
https://docs.github.com/en/free-pro-team@latest/github/building-a-strong-community/manually-creating-a-single-issue-template-for-your-repository

[sudiptog81]

Sure. I will address the comments in my next commit.

I think this is looking pretty good, just some minor suggestions that could also come later

[PeterDaveHello]

Ask for one more approval from @nodejs/docker 😃

@sudiptog81 would you squash these commits and rebase your branch base on the latest master branch? I can also help you do it if you want.

I'll do that as soon as able. Thanks for the approval!

Let's get it merged, and we'll see if there is anything we can improve in the usage.
