The primary interface for creating, manipulating, and executing Prism projects is the command line. The full list of commands are described in detail in the CLI section.
To create your first Prism project, navigate to your folder of choice and run the following command:
$ prism init --project-name my_first_project

Welcome to Prism, the easiest way to create clean, modular data pipelines
using Python!
To get started, navigate to your newly created project "my_first_project" and try
running the following commands:
prism compile
prism run
Consult the documentation here for more information on how to get started.

Happy building!

Again, the CLI section gives a much more comprehensive overview of how to use the command line to manipulate projects. But, if you're itching to get started and you want to execute this project right away, then navigate to that directory and use prism run:
$ cd my_first_project
$ prism run

The project itself doesn't do much. It only has one task, and this task simply creates a .txt file in the output folder containing the string Hello, World!.
Here's what the Prism graph looks like:
In the next section, we'll add some complexity and learn about tasks and targets.
