## Common Patterns

### CI/CD Pipeline

```bash
#!/bin/bash
set -e

# Add projects non-interactively

pakker add-prj --mr lithium --yes --no-deps

# Resolve dependencies
pakker update --all --yes

# Fetch files
pakker fetch

# Export for all platforms
pakker export --profile curseforge -o dist/curseforge.zip
pakker export --profile modrinth -o dist/modrinth.mrpack
pakker export --profile serverpack -o dist/server.zip
```

### Batch Updates

```bash
# Update all projects
pakker update --all --yes

# Fetch new versions
pakker fetch

# Export updated pack
pakker export --profile modrinth -o updated-pack.mrpack
```

### Platform Migration

```bash
# Add projects from new platform
pakker add-prj --mr sodium --cf sodium --yes
pakker add-prj --mr lithium --cf lithium --yes

# Export for both platforms
pakker export --profile curseforge -o cf-pack.zip
pakker export --profile modrinth -o mr-pack.mrpack
```

---

## Environment Variables

### Credentials

```bash
export CURSEFORGE_API_KEY="your-key"
