This includes source code, documentation, and any other necessary materials including external references that are required to understand the content.
 - There are clear learning objectives stated in the inaugural section of the README file. These objectives should be specific, measurable, achievable, relevant, and time-bound (SMART). They should provide a clear understanding of what a learner will be able to do after completing the educational unit. This should be emphasized inside the closing section of the README file, where a learner is encouraged to reflect on what they have learned and how they can apply it in practice. Regarding scope, each educational unit should be covered in one instructor lead lecturing session, which is typically 45-90 minutes.

This is particularly important for online learning, where a learner may not have direct access to a teacher or instructor. That being said, an educational unit is not like classical step-by-step tutorials, instead they require active engagement from a learner, who is expected to experiment with the provided material and reflect on the results.

This protects a book or course from becoming outdated too quickly. The educational unit can be updated independently of the rest of the material, ensuring that the content remains relevant and up-to-date.

 # Usage
 The UI is designed to be simple and intuitive. The main page contains a selection box with currently available domains (the _All Domains_ option is chosen by default). The rest of the home page lists all educational units filtered by domain. Each educational unit is represented as a clickable card that will open the respective repository in a new tab.
