    - syntax knowledge
-   - bits of deeper understanding of the semantics
-   - sources for further learning (docs and more)
-   - a useful application

    - room for own experiments

 Methods
 -------
 
+While all the action might be mostly between "you and your computer", we try to give
+you a feel that someone is guiding you in a real-world programming situation.
+You will be able to follow a train of thought from the first strategic decisions,
+to the selection process to find the most suitable Perl feature,
+then to the trying out of several ways to formulate it, up to the finishing edits
+of the implementation. Some evaluation helps you understand what has been achieved.
+
+That sounds like lot of text - but we actually tried to keep it informative and concise -
+advancing with a rather fast pace. Therefore we encourage you to read a chapter or
+paragraph repeatedly, as long you feel like not fully understanding it. We think
+that is way better than having to work through boring passages. Links to detailed
+information will be provided on the spot needed.
+
+The flip side of this practical, yet dense approach: you have to stick for the most
+part with the order of the content and won't be able to skip even several sentences.
+Because you might overlook this way an important feature, the next tho pages build upon.
+It is one program, that developes constantly from front to back. Some parts stay
+over long phases the same - other getting replaced quickly. While we strongly recommend
+to adapt the program to your wishes, you should be be aware that maintaining them
+through the whole tutorial might be a big extra task.
