@nichonien what's the rationale for having the code of conduct at the root and under apps/vc-api? In my opinion, just having it at the root would be sufficient. As a comparison, we only have one LICENSE file, which is at the root (as far as I can tell).

Yeah, I added it because we are proposing vc-api to OWF and if someone looks at the repo they should be able to find the code-of-conduct rather than going to the root. Also if we need to move the vc-api to separate repo then we won't need to add it again. We can do the same for LICENSE too. What do you think?

Sounds good to me
