 ## ✅ What We Built
 
 ### Core Features
+
 1. **Zero Configuration** - Works out of the box with sensible defaults
 2. **Fully Configurable** - VFS type, PRAGMA settings, logging options
 3. **TypeScript First** - Complete type safety and IntelliSense

-| **PRAGMA** | Hardcoded (MEMORY, NORMAL) | User configurable |
-| **VFS** | Hardcoded opfs-sahpool | User can choose (opfs-sahpool, opfs, memdb) |
-| **Pool Config** | Fixed (initialCapacity: 3) | Configurable |
-| **Console Filtering** | Always on | Optional (configurable) |
