title: How to use Apollo Studio to explore Dgraph
body: <p>I've setup a Dgraph using the docker version. I'm currently able to manipulate the schema and query the graph using Ratel (dgraphs' official tooling); but I want to be able to connect to my graph using Apollo Studio. I tried http://localhost:8080 and http://localhost:8080/graphql in the apollo studio but it can't connect. It was said somewhere in their forum that I need to setup apollo server in front of the dgraph to be able to use apollo studio. Can someone guide me on the steps needed to do so?</p>
