+# Pol.is Math Python Quick Start Guide
+
+This guide provides the essential steps to get started with the Python implementation of Pol.is math.
+
+## Environment Setup
+
+The Python implementation requires Python 3.8+ (ideally Python 3.12) and several dependencies.
+
+### Creating a New Virtual Environment
+
+It's recommended to create a fresh virtual environment:
+
+```bash
+# Navigate to the python_conversion directory
+cd math/python_conversion
+
+# Create a new virtual environment
+python3 -m venv new_polis_env
+
+# Activate the virtual environment
+source new_polis_env/bin/activate  # On Linux/macOS
+# or
+new_polis_env\Scripts\activate     # On Windows
+```
+
+Your command prompt should now show `(new_polis_env)` indicating the environment is active.
+
+### Installing Dependencies
+
+With your virtual environment activated, install the package and its dependencies:
+
+```bash
+# Install the polismath package in development mode
+pip install -e .
+
+# Install additional packages for visualization and notebooks
+pip install matplotlib seaborn jupyter
+```
+
+This will install the package in development mode with all required dependencies.
+
+## Running Tests
+
+### Using the Test Runner
+
+The most reliable way to test the system is using the simplified tests:
+
+```bash
+# With the virtual environment activated
+python run_tests.py --simplified
+```
+
+These tests run the core algorithms with minimal dependencies and are known to work correctly.
+
+You can also run other test types:
+
+```bash
+# Run only unit tests (Note: some may fail due to implementation differences)
+python run_tests.py --unit
+
+# Run demo scripts
+python run_tests.py --demo
+```
+
+### System Test
+
+To run a comprehensive system test with real data:
+
+```bash
+# Test with the biodiversity dataset (default)
+python run_system_test.py
+
+# Test with the VW dataset
+python run_system_test.py --dataset vw
+```
+
+Note: The system test is more prone to issues as it relies on specific attribute names and data structures. Check the `TESTING_LOG.md` file for known issues and their fixes.
+
+## Running Analysis Notebooks
+
+To run the biodiversity analysis directly without Jupyter:
+
+```bash
+# Navigate to the eda_notebooks directory
+cd eda_notebooks
+
+# Run the analysis script
+python run_analysis.py
+```
+
+This will:
+1. Load data from the biodiversity dataset
+2. Process votes and comments
+3. Run PCA and clustering
+4. Calculate representativeness
+5. Save results to the `output` directory
+
+To verify that the environment is set up correctly:
+
+```bash
+python run_analysis.py --check
+```
+
+To launch the notebook server (if you prefer interactive analysis):
+
+```bash
+# If you have Jupyter installed
+jupyter notebook biodiversity_analysis.ipynb
+```
+
+## Core Files to Understand
+
+Here are the key files to understand the system:
+
+1. **Package Structure:**
+   - `polismath/` - The main package directory
+   - `polismath/math/` - Core mathematical components
+   - `polismath/conversation/` - Conversation state management

+
+## Working with Real Data
+
+To work with your own data:
+
+1. Prepare your data in CSV format with the following structure:
+   - Votes: columns `voter-id`, `comment-id`, and `vote` (values: 1=agree, -1=disagree, 0=pass)
+   - Comments: columns `comment-id` and `comment-body`
+
+2. Use the Conversation class:
+   ```python
+   from polismath.conversation.conversation import Conversation
+
+   # Create a conversation
+   conv = Conversation("my-conversation-id")
+
+   # Process votes in the format that conv.update_votes expects:
+   votes_list = []
+   for _, row in votes_df.iterrows():
+       votes_list.append({
+           'pid': str(row['voter-id']),
+           'tid': str(row['comment-id']),
+           'vote': float(row['vote'])
+       })
+
+   # IMPORTANT: Update the conversation with votes and CAPTURE the return value
+   # Also set recompute=True to ensure all computations are performed
+   conv = conv.update_votes({"votes": votes_list}, recompute=True)
+
+   # If needed, explicitly force recomputation
+   conv = conv.recompute()
+
+   # Access results
+   rating_matrix = conv.rating_mat
+   pca_results = conv.pca
+   clusters = conv.group_clusters
+   representativeness = conv.repness
+   ```
+
+## Getting Help
+
+If you encounter issues:
+
+1. Check `TESTING_LOG.md` for known issues and their solutions
+2. Look at the simplified test scripts (`simplified_test.py` and `simplified_repness_test.py`) for reliable examples
+3. Try running `run_analysis.py --check` to verify your environment
+4. Examine error messages and try to isolate the problem
+5. The `run_system_test.py` script provides a good template for loading and processing real data
