+# Contributing to Veraison Documentation
+
+Thank you for your interest in contributing to the Veraison docs. This file gives a
+lightweight, focused workflow that helps maintainers review contributions quickly and
+ensures a consistent developer experience.
+
+Steps
+1. Fork the repository and create a branch named `docs/issue-<number>-<short-desc>`.
+2. Make small, focused commits. Prefer one logical change per commit.
+3. Run the provided scripts in `scripts/` to validate your environment and examples.
+   - `scripts/setup.sh` to install developer prerequisites (non-destructive; prompts before changes).
+   - `scripts/validate-setup.sh` to run pre-flight checks.
+   - `scripts/quick-start.sh` to run a minimal local demo (requires Docker).
+4. Update or add documentation under the appropriate folder (e.g., `api/`, `demo/`, `architecture/`).
+5. Add tests or checks where appropriate (examples validation, OpenAPI linting).
+6. Push your branch and open a Pull Request against `main` with the issue number in the title.
+
+Pull Request Checklist
+- [ ] I followed the contributing guidelines in this file.
+- [ ] I ran `scripts/validate-setup.sh` and fixed any issues.
+- [ ] The changes are described clearly in the PR description.
+- [ ] If the change affects examples or code, I added or updated tests where applicable.
+
+Notes
+- Keep changes minimal and avoid large refactors in the same PR.

+
+## Quick start
+
+This repository includes small helper scripts to improve the developer onboarding experience
+and address common setup/validation tasks. They are intentionally conservative and
+platform-guided. See `CONTRIBUTING.md` for the recommended workflow.
+
+1. Run a quick validation to check your environment:
+
+	```sh
+	scripts/validate-setup.sh
+	```
+
+2. If tools are missing, either follow the printed suggestions or use the guided setup:
+
+	```sh
+	scripts/setup.sh --dry-run
+	# or
+	scripts/setup.sh
+	```
+
+3. To run a minimal quick-start verification (requires Docker):
+
+	```sh
+	scripts/quick-start.sh
+	```
+
+These scripts are small helpers to make developer onboarding easier. They don't replace
+per-demo instructions; please check `demo/` for demo-specific steps (PSA and CCA demos).

+
+## Setup Issues
+
+### Missing Dependencies
+
+**Problem**: `scripts/validate-setup.sh` reports missing tools.
+
+**Solution**:
+```bash
+# Run the guided setup
+./scripts/setup.sh
+
+# Or install manually:
+# Ubuntu/Debian
+sudo apt-get update
+sudo apt-get install -y docker.io docker-compose-plugin protobuf-compiler shellcheck
+
+# macOS (using Homebrew)
+brew install docker docker-compose protobuf shellcheck
+
+# Verify installation
+./scripts/validate-setup.sh
+```
+
+### protoc Not Found
+
+**Problem**: `protoc: command not found`
+
+**Solution**:
+- **Ubuntu/Debian**: `sudo apt-get install -y protobuf-compiler`
+- **macOS**: `brew install protobuf`
+- **Manual**: Download from https://github.com/protocolbuffers/protobuf/releases
+
+### shellcheck Not Found
+
+**Problem**: `shellcheck: command not found`
+
+**Solution**:
+- **Ubuntu/Debian**: `sudo apt-get install -y shellcheck`
+- **macOS**: `brew install shellcheck`
+- **Windows (WSL)**: `sudo apt-get install -y shellcheck`
+
+## Docker Issues
+
+### Docker Permission Denied
+
+**Problem**: `Got permission denied while trying to connect to the Docker daemon socket`
+
+**Solution**:
+```bash
+# Add your user to the docker group
+sudo usermod -aG docker $USER
+
+# Log out and log back in, or run:
+newgrp docker
+
+# Verify
+docker ps
+```
+
+### Docker Compose Version Issues
+
+**Problem**: `docker-compose: command not found` or version conflicts
+
+**Solution**:
+```bash
+# Modern Docker includes compose as a plugin
+docker compose version
+
+# If using standalone docker-compose v1:
+python3 -m pip install --user docker-compose
+
+# Or install the plugin:
+sudo apt-get install -y docker-compose-plugin
+```
+
+### Port Already in Use
+
+**Problem**: `Bind for 0.0.0.0:8080 failed: port is already allocated`
+
+**Solution**:
+```bash
+# Find and stop the conflicting process
+sudo lsof -i :8080
+sudo kill <PID>
+
+# Or change the port in docker-compose.yml
+```
+
+## Platform-Specific Issues
+
+### Ubuntu/Debian
+
+**Issue**: Older package versions
+
+**Solution**:
+```bash
+# Add Docker's official repository for latest versions
+curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
+echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
+sudo apt-get update
+sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
+```
+
+### macOS
+
+**Issue**: Docker Desktop required
+
+**Solution**:
+- Install Docker Desktop from https://www.docker.com/products/docker-desktop
+- Or use alternatives like OrbStack or Colima
+
+**Issue**: Slow file I/O with Docker volumes
+
+**Solution**:
+- Use Docker Desktop's VirtioFS for better performance
+- Consider using named volumes instead of bind mounts
+
+### Windows (WSL2)
+
+**Issue**: WSL2 integration not working
+
+**Solution**:
+1. Ensure WSL2 is installed: `wsl --install`
+2. Enable WSL2 integration in Docker Desktop settings
+3. Restart Docker Desktop
+
+**Issue**: Line ending issues
+
+**Solution**:
+```bash
+# Configure git to handle line endings
+git config --global core.autocrlf input
+```
+
+## Demo Issues
+
+### PSA Demo Fails to Start
+
+**Problem**: Services fail to start or exit immediately
+
+**Solution**:
+```bash
+# Check logs
+cd demo/psa
+docker compose logs
+
+# Rebuild containers
+docker compose down
+docker compose build --no-cache
+docker compose up
+```
+
+### CCA Demo Missing Files
+
+**Problem**: Required data files or keys are missing
+
+**Solution**:
+```bash
+# Ensure you're in the correct directory
+cd demo/cca/prov-verif-e2e
+
+# Check that data/keys and data/templates exist
+ls -la data/keys/
+ls -la data/templates/
+```
+
+### Health Check Failures
+
+**Problem**: Services are running but health checks fail
+
+**Solution**:
+```bash
+# Manual health check
+curl http://localhost:8080/health
+
+# Check service logs for errors
+docker compose logs <service-name>
+
+# Wait longer for services to start
+sleep 10 && ./scripts/healthcheck.sh http://localhost:8080/health
+```
+
+## Build and Validation Issues
+
+### Make Validate Fails
+
+**Problem**: `make validate` exits with error
+
+**Solution**:
+```bash
+# This is expected if tools are missing
+# Install missing dependencies first
+./scripts/setup.sh
+
+# Then retry
+make validate
+```
+
+### Shellcheck Reports Issues
+
+**Problem**: `make shellcheck` reports warnings or errors
+
+**Solution**:
+- Review the reported issues in your shell scripts
+- Most are suggestions for better practices
+- Critical issues should be fixed before committing
+
+### OpenAPI Validation Fails
+
+**Problem**: API specs fail validation
+
+**Solution**:
+```bash
+# Check specific API directory
+cd api/challenge-response
+make
+
+# Review the error messages
+# Common issues: missing required fields, invalid references
+```

+# CCA Demo: Minimal Placeholder
+
+This folder contains a minimal placeholder `docker-compose.yml` that demonstrates how
+to provide a one-command demo orchestration for CCA attestation. It's intentionally
+a placeholder and should be replaced with real CCA verification services.
+
+## Quick Start
+
+```bash
+cd demo/cca
+docker compose up -d
+docker compose ps
+```
+
+## Health Checks
+
+```bash
+# Check CCA verifier
+../../scripts/healthcheck.sh http://localhost:8081/ || echo "Service starting..."
+
+# Check CCA provisioning
+../../scripts/healthcheck.sh http://localhost:8889/ || echo "Service starting..."
+```
+
+## Stop Services
+
+```bash
+docker compose down
+```
+
+## Next Steps
+
+For the full CCA demo with real attestation:
+- See [manual-end-to-end.md](manual-end-to-end.md) for detailed steps
+- Replace placeholder services with actual Veraison CCA components
+- Update docker-compose.yml with proper service images and configuration

+# Error Handling Guide
+
+This guide documents common error scenarios and their handling across Veraison documentation and demos.
+
+## Common Error Scenarios
+
+### 1. Invalid Token Format
+
+**Scenario**: Evidence token is malformed or uses incorrect encoding.
+
+**Detection**:
+```
+Error: failed to decode token: invalid format
+```
+
+**Resolution**:
+- Verify token is properly base64-encoded
+- Check token structure matches expected format (CoRIM, PSA, CCA)
+- Validate JSON structure for claims
+
+**Prevention**:
+- Use provided templates in `demo/*/data/templates/`
+- Validate tokens before submission
+
+### 2. Missing Endorsements
+
+**Scenario**: Reference values or endorsements not provisioned before verification.
+
+**Detection**:
+```
+Error: no matching reference values found
+Error: endorsement not found for platform
+```
+
+**Resolution**:
+1. Provision endorsements first using the provisioning API
+2. Verify endorsement was accepted: check API response
+3. Confirm evidence fields match provisioned reference values
+
+**Order of Operations**:
+```bash
+# 1. Provision endorsements
+curl -X POST http://localhost:8888/endorsement-provisioning/v1/submit \
+  -H "Content-Type: application/corim-unsigned+cbor; profile=http://arm.com/psa/iot/1" \
+  -d @corim.cbor
+
+# 2. Verify evidence
+curl -X POST http://localhost:8080/challenge-response/v1/newSession
+```
+
+### 3. Network Connectivity Issues
+
+**Scenario**: Services cannot communicate with each other.
+
+**Detection**:
+```
+Error: connection refused
+Error: dial tcp: lookup failed
+```
+
+**Resolution**:
+- Check all services are running: `docker compose ps`
+- Verify network configuration in docker-compose.yml
+- Check firewall rules
+- Use service names (not localhost) in Docker network
+
+### 4. Certificate/Key Errors
+
+**Scenario**: Invalid or missing cryptographic keys.
+
+**Detection**:
+```
+Error: failed to verify signature
+Error: certificate verification failed
+```
+
+**Resolution**:
+- Verify key files exist in `demo/*/data/keys/`
+- Check key format matches expected type (EC256, EC384, etc.)
+- Ensure public/private key pairs match
+- Validate key permissions (should be readable)
+
+### 5. Schema Validation Errors
+
+**Scenario**: API requests fail schema validation.
+
+**Detection**:
+```
+Error: invalid request: missing required field
+Error: schema validation failed
+```
+
+**Resolution**:
+- Review OpenAPI specifications in `api/*/schemas/`
+- Check request Content-Type headers
+- Validate JSON/CBOR structure
+- Use provided templates as reference
+
+## Error Handling Best Practices
+
+### For Demo Users
+
+1. **Check Prerequisites**:
+   ```bash
+   ./scripts/validate-setup.sh
+   ```
+
+2. **Start Services in Order**:
+   ```bash
+   # Start verification services first
+   docker compose up -d
+   
+   # Wait for health checks
+   ./scripts/healthcheck.sh http://localhost:8080/health
+   
+   # Then proceed with provisioning
+   ```
+
+3. **Enable Verbose Logging**:
+   ```bash
+   # Add to docker-compose.yml environment
+   VERAISON_LOG_LEVEL: debug
+   ```
+
+4. **Capture Logs**:
+   ```bash
+   docker compose logs > debug.log
+   ```
+
+### For Contributors
+
+1. **Validate Before Commit**:
+   ```bash
+   make validate
+   make shellcheck
+   ```
+
+2. **Test Error Paths**:
+   - Include negative test cases
+   - Document expected error messages
+   - Test with invalid inputs
+
+3. **Document Error Messages**:
+   - Clear, actionable error messages
+   - Include context and suggested fixes
+   - Reference relevant documentation
+
+## API Error Responses
+
+### Standard Error Format
+
+```json
+{
+  "error": "brief error description",
+  "detail": "detailed explanation of what went wrong",
+  "status": 400,
+  "suggestion": "what to do next"
+}
+```
+
+### Common HTTP Status Codes
+
+- `400 Bad Request`: Invalid input data, schema validation failure
+- `401 Unauthorized`: Missing or invalid authentication
+- `404 Not Found`: Resource (endorsement, session) not found
+- `409 Conflict`: Resource already exists
+- `500 Internal Server Error`: Service error, check logs
+- `503 Service Unavailable`: Service not ready, retry later
+
+## Debugging Tips
+
+### Enable Debug Mode
+
+For shell scripts:
+```bash
+bash -x ./scripts/setup.sh
+```
+
+For Docker services:
+```yaml
+environment:
+  DEBUG: "1"
+  LOG_LEVEL: "debug"
+```
+
+### Inspect Service State
+
+```bash
+# Check service health
+docker compose ps
+
+# View service logs
+docker compose logs -f <service>
+
+# Execute commands in container
+docker compose exec <service> sh
+
+# Inspect network
+docker network inspect <network-name>
+```
+
+### Validate Data Files
+
+```bash
+# Check JSON syntax
+jq . < data/templates/psa-claims.json
+
+# Validate CBOR (requires cbor-diag)
+cbor2diag < data.cbor
+
+# Check file permissions
+ls -la data/keys/
+```
+
+## Reporting Issues
+
+When reporting errors, include:
+
+1. **Environment Information**:
+   ```bash
+   ./scripts/validate-setup.sh
+   docker --version
+   docker compose version
+   ```
+
+2. **Complete Error Messages**:
+   - Full command that failed
+   - Complete error output
+   - Relevant log excerpts
+
+3. **Steps to Reproduce**:
+   - Starting state
+   - Exact commands run
+   - Expected vs actual behavior
+
+4. **Context**:
+   - Which demo (PSA, CCA)
+   - Platform (Ubuntu, macOS, Windows/WSL)
+   - Any modifications made

Subject: [PATCH 4/6] fix: use pip for docker-compose in CI instead of
 docker-compose-plugin

The docker-compose-plugin package is not available on all Ubuntu versions
in GitHub Actions. Switch to installing docker-compose via pip which is
more widely compatible across different Ubuntu versions.

Subject: [PATCH 5/6] fix: simplify CI dependencies, rely on pre-installed
 docker

GitHub Actions runners have Docker pre-installed. The docker-compose pip
installation was failing due to old PyYAML compatibility issues. Since our
validation scripts only check for tool presence and don't run containers
in CI, we can rely on the pre-installed Docker and skip the problematic
docker-compose installation.

Subject: [PATCH 6/6] fix: validate script supports both docker-compose v1 and
 v2

GitHub Actions and modern Docker installations use Docker Compose v2
(docker compose plugin) instead of the standalone docker-compose v1.
Updated validation to check for both versions and made protoc/shellcheck
warnings instead of failures since they're optional tools.
