Can you also delete the `.clang-format` file? Can you merge master and address comments? @prajvalgupta can you address comment above? Hey. @WillAyd  Can I pick this up? Also what did you mean by this 

> Can you merge master and address comments?

I am new to contributing and didn't understand what this meant. can you merge master

```git merge upstream/master```

and for each comment above you need to either fix or comment what is the issue I think this is stale as it hasn't been updated since first posting. @punndcoder28 if you'd like to take over you should get a copy of master locally on your own branch and merge these changes in. Can definitely take a look then

Of course @prajvalgupta if you are still actively working this please let us know
