@amitsin6h It is recommended to work on a difficulty/newcomer issue first. You can find them at https://coala.io/newcomer. Also, head to https://coala.io/chat and say "Hello World" if you haven't joined the organization yet. Welcome!!

@prnvdixit I have been assigned this in gitter chat

[prnvdixit]

That's great.... This issue is also of difficulty/newcomer IMO (probably), maybe you can submit a PR for this right away... Though, it's still recommended to do a newcomer issue first before attempting any higher difficulty issue 😄

[jayvdb]

As this is very high importance, if you dont finish it within 24 hours, we'll close your PRs and let someone else do it.

[amitsin6h]

@jayvdb am gonna do it.

[yashovardhan]

@amitsin6h are you going to complete it?

[ihsraham]

If he's not working on it I would like to 😄

@jayvdb you might assign this to me in that case

[jayvdb]

Reassigned.
