Peblio provides an easier way to write about and teach code. Peblio pages are called PEBLS (pronounced pebbles) and they can include different media like text, videos, websites, questions, and code in different languages that can be written, and executed in our editor widgets. This guide is written on a pebl and it includes videos and instructions for creating content with Peblio and using Peblio in your classroom.
