### What are the differences between "Module" and "Module Template"?

#### Module Template

Module template is a group of solidity code. If it is the same module template, it means it is the same ABI and byte code.

#### Module

Module consists of **module template** and **arguments of constructor**. 

When you deploy module, entity is generated. This entity has each attributes (state, contract address, etc.).
