	Learning
	- Technical
	- Use stderr and stdout properly (60% content for this 5w1h) (why do we need stderr, redirection, identify)
	- Use feature toggles
	- Write modular code in pkg dir so that anybody can import and use it (Eg helm, kubectl)
	- Easy dev setup (Makefile)
	- Logging at different log level (--debug flag)
	- 12 factor app (file, env, flag)
	- hyperfine for benchmark
	- NonTechnical
