This is a book for beginners who are looking to learn Ruby for writing Ruby on Rails applications. We start from zero, and build on the basics of the command line, through installing your development environment and then into the basics of Ruby.
No up-front knowledge is required, though understanding the basics of HTML and CSS will help.
By the end of the book you'll have built your first web app, a basic blog where you can write posts.
The book is 140 pages, and available in PDF and EPUB formats, including a dark mode PDF.
