This may not need to be done if #222 is fix by using upstream properly.

[ishanSrt]

not a bug in upstream, this issue could be held off for the while

[jayvdb]

If upstream has tests, and we remove our copy of their code, we dont need tests for their code.

@jayvdb upstream has tests
what do you mean by remove our copy of their code??

#222

We have a copy of their code.

@jayvdb I know that. But what do you mean by remove the copy of the code? How will quickstart function without that?
