How to set nakama development environment on local machine

I have setup of nakama server and cockroach db on my local machine but i did not find how to start with back-end new project development using nakama server.

@kmsudhir The best place to look if you want to write server logic specific to your game is the runtime page of our docs:

It includes instructions on where to place your modules to be loaded by the server and what the minimal code you need to write looks like to run some logic. I can give more help but you’d need to offer more specific questions I think.
