@azmaktr there is already a code-of-conduct as a folder at the root, do you wish to add another at the root? Or maybe copy the one mentioned prior to the root as well?

@azmaktr can we merge this?

@Rubix982 This is to put a checkmark on the github's standards for an open source repository.

We can perhaps have both of them at the same time.
