Document how to run locally

[bertday]

I was looking for some instructions on how to run the app locally and didn't see anything in README.md. Did I maybe just miss this, or can I help with adding some notes? 😄

@rbrtmrtn I get the impression you are looking at the main branch; you might have better luck with develop. I can't speak to all the branch management, but my impression is that main is pretty stale (but represents the production deploys?) while develop is the destination for merging various feature branches.
In the develop branch README, this is at the end of the setup section:

After that you should be able to serve the backend and frontend by running in both server and client folders.
yarn run serve

I think that was added when @hcdeng and I joined about a month ago.

IOW, execute yarn run serve (or just yarn serve) in the packages/server directory to start the API backend on port 3000, and the same command in the packages/client directory to start the app on port 8080.

@smattingly Thank you for following up on this and for the helpful notes on main vs. develop. I'll give this another try on develop using that README!
