Design key-value store like Redis but link points to introduction

Created by: nitinsurana

Hi Thanks for this awesome primer. I love it! While surfing through the primer, I found this https://github.com/donnemartin/system-design-primer/blob/master/README.md#additional-system-design-interview-questions which has Design a key-value store like Redis, but the slidershare.net link points to a slide deck Introduction of Redis and not really the design/architecture. Technically, it should point to information required to create a distributed key-value store.
