Add comprehensive experimental dashboard and RAG testing suite

- Implement 4 experiment types: input/output guardrails, hyperparameters, context window
- Add interactive GUI dashboard with system information and database stats
- Enhance main interface with improved chat layout and explanatory content
- Update README with comprehensive documentation
- Clean up code by removing unused imports and JSON file operations

-# Knowledge Retrieval System
+# 🎓 University Knowledge Retrieval System
 
+A comprehensive Retrieval-Augmented Generation (RAG) system for university data with advanced guardrails and experimental validation.
 
-## IMPORTANT: 
-Currently api key for hugging face is expected in secrets_local.py file, with definition under HF=.
+## 🌟 Features
 
-## Quick Start via Frontend
+- **Interactive Chat Interface**: Natural language queries about university data
+- **Advanced Guardrails**: Input/output security with malicious content filtering
+- **Experimental Dashboard**: Comprehensive testing suite for RAG validation
+- **Real Database**: 6,000+ students, 1,300+ faculty, 2,600+ courses
+- **Vector Search**: Semantic search using ChromaDB and Sentence Transformers
 
+## 🚀 Quick Start
+
+### Prerequisites
+- Python 3.8+
+- Hugging Face API Token
+
+### Installation
+
+1. **Clone and setup**:
 ```bash
-# Installieren
-pip install streamlit
+git clone <repository-url>
+cd projekt
+pip install -r requirements.txt
+```
 
-# Starten
-streamlit run app.py
+2. **Configure API Key** (choose one):
+   - Create `secrets_local.py`: `HF = "your_hugging_face_token"`
+   - Or set environment variable: `HF_TOKEN=your_token`
 
-# Beenden
-Ctrl + C
+3. **Run the application**:
+```bash
+streamlit run app.py
 ```
-## TODO Frontend 
-- Switch Language to English 
 
-## TODO Input 
-- precompile regex statements 
+## 📊 System Components
+
+### Chat Interface
+- Natural language queries about university data
+- Real-time RAG pipeline with source citations
+- Input/output guardrails for security
+
+### Experimental Dashboard
+Four comprehensive test suites:
+1. **Input Guardrails**: Tests against malicious inputs (SQL injection, PII extraction)
+2. **Output Guardrails**: Validates response quality and detects hallucinations
+3. **Hyperparameters**: Analyzes temperature, top-k, top-p effects on diversity
+4. **Performance**: Context window optimization and response quality metrics

+
+**Dependencies** (requirements.txt):
+- streamlit==1.37.0
+- sentence-transformers==5.1.0
+- chromadb==1.0.21
+- Faker==15.3.4 (for database generation)
+- huggingface-hub==0.34.4
+- nltk, numpy, scikit-learn
+
+## 🎯 Usage Examples
+
+**Student Queries**:
+- "What courses is Maria taking?"
+- "Who are the students in computer science?"
+
+**Faculty Queries**:
+- "Who teaches in the engineering department?"
+- "Show me all professors"
+
+**Course Queries**:
+- "What courses are available?"
+- "Who teaches advanced mathematics?"
+
+## 🧪 Running Experiments
+
+Access via the "Experiments" tab in the web interface, or run individually:
+
+```bash
+cd experiments
+python experiment_1_input_guardrails.py
+python experiment_2_output_guardrails.py
+python experiment_3_hyperparameters.py
+python experiment_4_context_window.py
+```
+
+## 🔒 Security Features
+
+- **Input Validation**: SQL injection prevention, malicious prompt detection
+- **Output Filtering**: PII redaction, hallucination detection, relevance checking  
+- **Content Sanitization**: Automatic cleaning of responses and database content
+
+## 📈 Database Statistics
+
+- **Students**: 6,398 records with realistic personal data
+- **Faculty**: 1,297 professors across multiple departments
+- **Courses**: 2,600 courses linked to faculty
+- **Enrollments**: 19,443 student-course relationships
