 5. **Publishing** organized weekly digests using mdBook
 
-## 🚀 Quick Start
-
-### Prerequisites
-
-- Python 3.7+
-- mdBook (for building the site)
-- Optional: `html2text` for better Markdown conversion
-  ```bash
-  pip install html2text
-  ```
-
-### Setup
-
-1. **Clone the repository**
-   ```bash
-   git clone <your-repo-url>
-   cd pgweekly
-   ```
-
-2. **Create your prompt file** (first time only)
-   ```bash
-   cp QUICK_PROMPT.template QUICK_PROMPT.txt
-   ```
-   > **Important:**
-   > - `QUICK_PROMPT.template` is the version-controlled template
-   > - `QUICK_PROMPT.txt` is your personal working copy (gitignored)
-   > - Always copy from the template when starting fresh
-   > - You can customize `QUICK_PROMPT.txt` without affecting the repository
-
-3. **Build the book** (optional, to view existing content)
-   ```bash
-   mdbook build
-   mdbook serve  # View at http://localhost:3000
-   ```

-## 📖 Advanced Topics
-
-### Batch Processing
-
-Process multiple threads at once:
-
-```bash
-# Fetch multiple threads
-for thread_id in "id1" "id2" "id3"; do
-    python3 tools/fetch_data.py --thread-id "$thread_id"
-done
-```
-
-Then use the batch processing prompt in `BLOG_GENERATION_PROMPT.md`.
-
-### Custom Prompts
-
-Customize `QUICK_PROMPT.txt` for your needs:
-- Adjust writing style (formal, conversational)
-- Focus on specific aspects (performance, security)
-- Target specific audiences (DBAs, developers, beginners)
-- Change blog length or depth
-
-### Comparing Patches
-
-When multiple patch versions exist (v1, v2, v3), the agent will automatically:
-```bash
-diff -u attachments/v1-*.patch attachments/v2-*.patch
-```
-
-This helps explain how the solution evolved based on community feedback.
