# Vorwort

Dieses Online-Skript stellt eine strukturierte und didaktisch aufbereitete Sammlung der Materialien aus dem Modul [**Web Engineering**](https://www.hs-osnabrueck.de/module/44b0585/) dar, das ich an der Hochschule Osnabrück anbiete.

Für die Einarbeitung in die Websprachen HTML, CSS und JavaScript empfehle ich zusätzlich zu diesem Buch allen Studierenden die Dokumentationsplattform [MDN Web Docs](https://developer.mozilla.org/en-US/). Sie beinhaltet erstklassige Artikel zur Einführung der wichtigsten Konzepte rund um die drei Sprachen des Web.

Speziell die Guides zu den Themen [HTML](https://developer.mozilla.org/en-US/docs/Learn/HTML), [CSS](https://developer.mozilla.org/en-US/docs/Learn/CSS) und [JavaScript](https://developer.mozilla.org/en-US/docs/Learn/JavaScript) empfehle ich als Pflichtlektüre.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://web.datalit.de/vorwort.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
