Installation or Setup

Visit https://download.racket-lang.org and choose between the two available distributions:

• Racket is the main distribution, it comes with several additional packages like math/number-theory as well as the DrRacket IDE.

• Minimal Racket is far smaller and comes only with the needed packages.

To run a program, open DrRacket, enter the program starting with #lang racket, and click the Run button near the top-right corner.

Installation steps for Windows:

The installation is very simple. If you are used to this kind of thing, just go to https://download.racket-lang.org, then download and run the installer. A more detailed step-by-step walkthrough is detailed afterwards, if you prefer.
