Beyond the README

• Implementation Details: Parameter Vector and other tricky components
• Walkthroughs and Tutorials: Line-by-line demos
• Concepts: What's a logic program? What's a graph? What's being learned? What are the features?
• Using Features in ProPPR: How to pair the right feature with the right program
• Best Practices: How do I build a good dataset?
• Troubleshooting: Common error messages and how to diagnose them

Contributing to ProPPR

• Commit Checklist: How to run tests and avoid breaking the build
• API Use Cases: In theory, when we make something possible in the API, we'll document it here.
