 ## Content 📖
 
-Exercises are progressive in difficulty. They are designed to learn the fundamentals of blockchains as well as the main technologies and tools used in the industry.
+Exercises increase progressively in difficulty. They are designed to teach the fundamentals of blockchains, as well as the main technologies and tools used in the industry.
+
+The content is organized into *quests*, that offer several exercises on a topic, *raids*, that are larger collaborative exercises, and *projects*, to explore further. It should take two to three weeks to complete the *quests* and *raids*.
 
 - Quest 1: Experiment with basic Bitcoin transactions
 - Quest 2: Learn fundamental cryptography

 ## Tests ⚙️
 
-Within the `tests/` folder, `run.sh` builds a docker image and runs the tests. Solutions are expected to be in a `tests/student` folder. For each available solution file, the appropriate test will be launched individually. The docker daemon or docker desktop needs to be running.
