Setting up the Git Repo
We're sure you can handle creating a new empty Git repository. But once you have your initial
commit with a README.md, .gitignore, etc., you'll want to pull in the common KillrVideo 
dependencies that live in other Git repositories. The repositories you'll want to pull in 
are:
- killrvideo-service-protos: This is where the gRPC service 
definitions that you'll be implementing are kept, defined in .protofiles. You'll be using the Protobufs from here to generate code.
Using Git Subtrees for Dependencies
In other microservice implementations, we've decided to use git subtree to pull in these
dependencies rather than submodules. Here's a pretty good overview of subtrees if
you're not familiar. Here's an example of the commands to add those subtrees to your 
repository under the /lib folder:
# Add killrvideo-service-protos under lib/killrvideo-service-protos
git subtree add --prefix lib/killrvideo-service-protos git@github.com:KillrVideo/killrvideo-service-protos.git master --squashLater if you need to update those dependencies you can just use the same commands as above,
only doing a git subtree pull instead of git subtree add.
