Req: Enhance the documentation

[maradanasai]

Hi @criyle thanks for providing this. I’m not from go background but very much interested in looking at details in this repo. Can you please help with sharing the architecture/flow design, purpose of every service and its components in detail will help understand a lot.

Also, may I know how we can scale these services horizontally and make it work.

Thanks in advance!!

api gateway:

• serves the static files for SPA website
• /api/ws web socket endpoint for receiving real-time update on submissions
• /api endpoint for AJAX calls, converting the request to gRPC calls to demo server including submit new code and get list of submissions

demo server:

• connect MongoDB for storage
• gRPC server for api calls from the api gateway to submit code for execution
• gRPC streaming server for api gateway to push updates via web socket
• gRPC streaming server for judger endpoint to push new submissions for execution

judger:

• connect demo server via gRPC streaming endpoint for receiving new submissions
