This is a GitHub repository for auto-dop-banner, which automates the creation of markdown files for the 100 Days of Productivity challenge. The project was inspired by Alexander Kallaway's 100-Days-of-Code. To get started, users can either generate a template from the repository or manually install @erutidians/auto-dop. They should then create an index.js file and include their name, GitHub username, start date, and round number if applicable. Users can use commands to create markdown files for today, yesterday, tomorrow, or any specific date. The repository includes information on how to contribute to the project and a list of challengers who have used auto-dop.
