Fix page numbering: Switch to user-friendly 1-based indexing

**Problem**: Zero-based page numbers were confusing for users who naturally
think of pages starting from 1.

**Solution**:
- Updated `parse_pages_parameter()` to convert 1-based user input to 0-based internal representation
- All user-facing documentation now uses 1-based page numbering (page 1 = first page)
- Internal processing continues to use 0-based indexing for PyMuPDF compatibility
- Output page numbers are consistently displayed as 1-based for users

**Changes**:
- Enhanced documentation strings to clarify "1-based" page numbering
- Updated README examples with 1-based page numbers and clarifying comments
- Fixed split_pdf function to handle 1-based input correctly
- Updated test cases to verify 1-based -> 0-based conversion
- Added feature highlight: "User-Friendly: All page numbers use 1-based indexing"

**Impact**: Much more intuitive for users - no more confusion about which page is "page 0"\!

+# Claude Desktop MCP Configuration
+
+This document explains how the MCP PDF Tools server has been configured for Claude Desktop.
+
+## Configuration Location
+
+The MCP configuration has been added to:
+```
+/home/rpm/.config/Claude/claude_desktop_config.json
+```
+
+## PDF Tools Server Configuration
+
+The following configuration has been added to your Claude Desktop:
+
+```json
+{
+  "mcpServers": {
+    "pdf-tools": {
+      "command": "uv",
+      "args": [
+        "--directory",
+        "/home/rpm/claude/mcp-pdf-tools",
+        "run",
+        "mcp-pdf-tools"
+      ],
+      "env": {
+        "PDF_TEMP_DIR": "/tmp/mcp-pdf-processing"
+      }
+    }
+  }
+}
+```
+
+## What This Enables
+
+With this configuration, all your Claude sessions will have access to:
+
+- **extract_text**: Extract text from PDFs with multiple method support
+- **extract_tables**: Extract tables from PDFs with intelligent fallbacks
+- **extract_images**: Extract and filter images from PDFs
+- **extract_metadata**: Get comprehensive PDF metadata and file information
+- **get_document_structure**: Analyze PDF structure, outline, and fonts
+- **is_scanned_pdf**: Detect if PDFs are scanned/image-based
+- **ocr_pdf**: Perform OCR on scanned PDFs with preprocessing
+- **pdf_to_markdown**: Convert PDFs to clean markdown format
+
+## Environment Variables
+
+- `PDF_TEMP_DIR`: Set to `/tmp/mcp-pdf-processing` for temporary file processing
+
+## Backup
+
+A backup of your original configuration has been saved to:
+```
+/home/rpm/.config/Claude/claude_desktop_config.json.backup
+```
+
+## Testing
+
+The server has been tested and is working correctly. You can verify it's available in new Claude sessions by checking for the `mcp__pdf-tools__*` functions.
+
+## Troubleshooting
+
+If you encounter issues:
+
+1. **Server not starting**: Check that all dependencies are installed:
+   ```bash
+   cd /home/rpm/claude/mcp-pdf-tools
+   uv sync --dev
+   ```
+
+2. **System dependencies missing**: Install required packages:
+   ```bash
+   sudo apt-get install tesseract-ocr tesseract-ocr-eng poppler-utils ghostscript python3-tk default-jre-headless
+   ```
+
+3. **Permission issues**: Ensure temp directory exists:
+   ```bash
+   mkdir -p /tmp/mcp-pdf-processing
+   chmod 755 /tmp/mcp-pdf-processing
+   ```
+
+4. **Test server manually**:
+   ```bash
+   cd /home/rpm/claude/mcp-pdf-tools
+   uv run mcp-pdf-tools --help
+   ```

 - **Document Analysis**: Extract structure, metadata, and check if PDFs are scanned
 - **Image Extraction**: Extract images with size filtering
 - **Format Conversion**: Convert PDFs to clean Markdown format
+- **URL Support**: Process PDFs directly from HTTPS URLs with intelligent caching
 - **Smart Detection**: Automatically detect the best method for each operation
+- **User-Friendly**: All page numbers use 1-based indexing (page 1 = first page)
+
+## URL Support
+
+All tools support processing PDFs directly from HTTPS URLs:
+
+```bash
+# Extract text from URL
+mcp_pdf_tools extract_text "https://example.com/document.pdf"
+
+# Extract tables from URL  
+mcp_pdf_tools extract_tables "https://example.com/report.pdf"
+
+# Convert URL PDF to markdown
+mcp_pdf_tools pdf_to_markdown "https://example.com/paper.pdf"
+```
+
+**Features:**
+- **Intelligent caching**: Downloaded PDFs are cached for 1 hour to avoid repeated downloads
+- **Content validation**: Verifies content is actually a PDF file (checks magic bytes and content-type)
+- **Security**: HTTPS URLs recommended (HTTP URLs show security warnings)
+- **Proper headers**: Sends appropriate User-Agent for better server compatibility
+- **Error handling**: Clear error messages for network issues or invalid content
