-In this lesson, you'll learn how to create a simple smart contract program on the Gear platform. The program will promptly respond with a friendly "Hello" message upon receiving any incoming message. The lesson describes the step-by-step process of creating a new project, adding dependencies, writing code for the program entry point and building the project. It also explains the purpose and use of the [`msg`](https://docs.gear.rs/gstd/msg/) messaging module from the [`gstd`](https://docs.gear.rs/gstd/) library. We'll conclude with instructions for testing the program.
-By the end of this tutorial, you'll have learnt how to create a basic smart contract program and gained an understanding of the libraries and tools of the Gear platform.
