-## Background Story Used
-
-This project utilizes a futuristic cyberpunk scenario to simulate a cybercrime investigation. Detective Y investigates a complex ransomware attack targeting robotics engineer Z by "The Serpent," who employs advanced techniques to encrypt and steal research data. This scenario serves as the knowledge base for the RAG system.
-
-## Story based Questions
-
-The RAG system answers questions based on the provided cyber forensics scenario. Examples:
-
-**In-Text Questions:**
-
-1.  What type of cyberattack did Detective Y investigate?
-2.  What was the victim's profession?
-3.  Where was the remote server located that led to the perpetrator's arrest?
-
-**Out-of-Text Questions (Answers not in the text):**
-
-1.  What specific encryption algorithm did The Serpent use?
-2.  What was the name of the university where the security breach occurred?
-3.  Did Detective Y's team collaborate with external experts?
+6.  **Provide your knowledge base:** Add a cell to define `document_text` (the scenario).
+7.  **Run the code:** Execute the cells to interact with the RAG system.
