I am using Julia for the first time to work on an optimization project. Is there a manual or guide which has information wrt how to declare indices, parameters, decision variable, objective function, and constraints.
Thanks for your time.

Welcome to the discourse forum!
The main optimization package in julia is JuMP, it’s an common interface for various solvers, so starting with the guide can be helpful.

There is also this book which is a great resource:
