Now that you've set up your computer and your EV3 brick, you're ready to start writing programs.
To make it easier to create and manage your programs, let's first have a quick look at how MicroPython projects and programs for your EV3 robots are organized.
Programs are organized into *project folders*, as shown below. A project folder is a directory on your computer that contains the main program (**main.py**), and other optional scripts or files. This project folder and all of its contents will be copied to the EV3, where the main program will be run.
This page shows you how to create such a project and how to transfer it to the EV3.

Connecting to the EV3 brick with Visual Studio Code
-----------------------------------------------------------
You'll now learn how to transfer your project to the EV3 brick and run the main program.
To be able to transfer your code to the EV3 brick, you'll first need to connect the EV3 brick to your computer with the mini-USB cable and configure this connection with Visual Studio Code. To do so:
First, make sure that your EV3 is turned on and that it is connected to your computer. Then, follow the steps below to configure the connection.
- Turn the EV3 brick on
- Connect the EV3 brick to your computer with the mini-USB cable
- Configure the USB connection as shown:

Running a program without a computer
-----------------------------------------------------------
You can run previously downloaded programs directly from the brick.
After you've downloaded your project to your EV3 brick, you can restart it even when it is not connected to a computer. To do so, find the file using the *file browser* and use the *Enter* key to start the program.
To do so, find the program using the *file browser* on the EV3 screen and use the center button key to start the program.
