+# Brevet Card PDF Generator
+
+LaTeX-based generator for Audax Randonneurs Deutschland brevet cards with front and back sides for duplex printing.
+
+## Quick Start
+
+```bash
+# Build everything and generate both PDFs
+make build
+
+# The PDFs will be created as:
+# - brevetkarte.pdf (front side with participant info)
+# - brevetkarte-rueckseite.pdf (back side with control points)
+```
+
+## Prerequisites
+
+- Docker
+- Make
+
+## Usage
+
+### Build Both PDFs
+```bash
+make build
+```
+
+This will:
+1. Build the Docker image with TeXLive
+2. Compile `brevetkarte.tex` to `brevetkarte.pdf` (front side)
+3. Compile `brevetkarte-rueckseite.tex` to `brevetkarte-rueckseite.pdf` (back side)
+
+### Build Individual Sides
+
+```bash
+# Just build front side
+make build-front
+
+# Just build back side
+make build-back
+
+# Build both sides (without rebuilding Docker image)
+make build-pdf
+```
+
+### Other Commands
+
+```bash
+# Just build the Docker image
+make build-image
+
+# Open interactive shell in container
+make shell
+
+# Clean generated files (.aux, .log, .pdf)
+make clean
+
+# Clean everything including Docker image
+make clean-all
+
+# Rebuild from scratch
+make rebuild
+
+# Show help
+make help
+```
+
+## Files
+
+- `brevetkarte.tex` - LaTeX source for the front side (participant info)
+- `brevetkarte-rueckseite.tex` - LaTeX source for the back side (control points)
+- `cyclist-logo.png` - Audax Randonneurs logo (extracted from original)
+- `Dockerfile` - Docker image definition with TeXLive
+- `Makefile` - Build automation
+- `Brevet200km_2025_09_20_Namensseite_blanko.pdf` - Original front side template
+- `Brevet200km_2025_09_20_Kontrollseite.pdf` - Original back side template
+
+## Output
+
+### Front Side (brevetkarte.pdf)
+Contains two identical brevet cards that can be cut in half. Each card includes:
+- Participant information fields (Name, Address, etc.)
+- Event details (200km "Auf eine Pommes nach Belgien")
+- Randonneur Mondiaux rules
+- Homologation section
+- Start time: 8:30
+
+### Back Side (brevetkarte-rueckseite.pdf)
+Contains control points table (4 columns × 6 rows):
+- **Rows 1-3**: Control points for upper card
+  - Nr. 1: Start (Km 0 - Unisport, Bonn)
+  - Nr. 2: Km 57 - Nationalpark-Tor, Heimbach
+  - Nr. 3: Km 100 - Friterie "Au Petit Creux", Waimes
+  - Nr. 4: Km 165 - Mahlberg
+  - Nr. 5: Km 205 - Finish (Unisport, Bonn)
+- **Rows 4-6**: Control points for lower card (same as above, but Nr. 5: Km 214)
+- Empty columns for stamps/signatures
+- Control question for verification
+
+## Duplex Printing
+
+The PDFs are designed for duplex (double-sided) printing:
+1. Print `brevetkarte.pdf` on one side
+2. Print `brevetkarte-rueckseite.pdf` on the reverse side
+3. The columns and rows are aligned so that:
+   - Front side columns match back side columns
+   - Upper card (rows 1-3) aligns with front side upper card
+   - Lower card (rows 4-6) aligns with front side lower card
+4. Cut the sheet in half horizontally to create two separate brevet cards
+
+## Customization
+
+Edit `brevetkarte.tex` to modify front side:
+- Event name, date, and location
+- Distance (200km)
+- Start time
+- Club information
+- Brevet number format
+
+Edit `brevetkarte-rueckseite.tex` to modify back side:
+- Control point locations
+- Control times (von/bis)
+- Distances
+- Control questions
