 # phpdb-adapter-sqlite
 
-This package provides SQLite support for php-db.
+<!-- markdownlint-disable MD013 -->
+
+This package provides [SQLite][sqlite] support for [php-db][php-db], which is a continuation of [laminas-db][laminas-db].
+
+[![Build Status](https://github.com/php-db/phpdb-sqlite/actions/workflows/continuous-integration.yml/badge.svg)](https://github.com/php-db/phpdb-sqlite/actions/workflows/continuous-integration.yml)
+
+## Prerequisites
+
+You'll need the following to use the package:
+
+- PHP 8.2 or above with the [PDO][php-pdo-extension] and [PDO SQLite][php-pdo-sqlite-extension] extensions
+- [Composer][composer] installed globally
+
+## Quick Start
+
+To get started with the project, add it to your project with the following command:
+
+```bash
+composer require php-db/phpdb-sqlite
+```
+
+## Contributing
+
+Please be sure to read the [contributor's guide](https://github.com/php-db/.github/blob/main/CONTRIBUTING.md) for general information on contributing.
+This section outlines specifics for php-db.
+
+### Test suites
+
+The `phpunit.xml.dist` file defines two test suites, "unit test" and "integration test".
+You can run one or the other using the `--testsuite` option to `phpunit`:
+
+```bash
+./vendor/bin/phpunit --testsuite "unit test" # unit tests only
+./vendor/bin/phpunit --testsuite "integration test" # integration tests only
+```
+
+Unit tests do not require additional functionality beyond having the appropriate database extensions present and loaded in your PHP binary.
