# Library

Every book we package as a skill, grouped by the place a product breaks. A book can sit under two clusters. Search by book, author or problem, or filter by cluster.

Bundles are pre-filled carts. The price comes from how many skills you take: see [/bundles](/bundles) and [/pricing](/pricing).

## Clusters

- **Validation**: Does anyone want it?
- **Product**: What do we build, and what do we deliberately not build?
- **Design**: Why does it look self-built?
- **Activation**: Why don’t they reach the first win?
- **Positioning**: What is this, and who is it for?
- **Pricing**: What is it worth?
- **Go-to-Market**: Which channel brings the first users?
