 Useful utilities to augment [sqflite](https://pub.dev/packages/sqflite). Designed to be unobtrusive helpers, so you still access sqflite directly (not a wrapper).
 
-## Features
+## Usage
 
-- Functions for working with `bool` values ([sqflite does not support bool](https://github.com/tekartik/sqflite/blob/master/sqflite/doc/supported_types.md#supported-sqlite-types))
+### Bool utilities
 
-## Usage
+Sqflite does not support the `bool` type ([reference](https://github.com/tekartik/sqflite/blob/master/sqflite/doc/supported_types.md#supported-sqlite-types)).
