Rad UI is built with React and TypeScript. If you are not familiar with TypeScript, we recommend you to first learn the basics of TypeScript and JavaScript. A primer on HTML and CSS is also recommended. It might be challenging to learn all of these at once, so we recommend you to first learn the basics of HTML, CSS, and JavaScript, and then learn TypeScript. If you up for a challenge and would like to pick these skills up along the way, that is also possible, but it might take quite a while.
Once you are familiar with the basics of TypeScript, JavaScript, HTML, and CSS, you can start learning React. We recommend you to start with the official React tutorial. It is a great way to get familiar with React and its concepts. Once you are familiar with React, you can start using/contributing Rad UI.
Once your prerequisites are covered and you played around with the components in the Playground and feel right at home, you can start contributing to Rad UI.
