[`@serenity-js/core`](https://serenity-js.org/api/core/) provides foundational building blocks of the [Serenity/JS](https://serenity-js.org)
ecosystem, enabling clean, expressive, and highly maintainable test automation based on the [Screenplay Pattern](https://serenity-js.org/handbook/design/screenplay-pattern/).
This package provides APIs and extension points used across all [Serenity/JS modules](https://serenity-js.org/api/).

## Features

- **Core APIs** for implementing the [Screenplay Pattern](https://serenity-js.org/handbook/design/screenplay-pattern/) in automated tests.
- **Actor lifecycle and abilities management** for clear, maintainable test orchestration.
- **Flexible integration points** with [test runners](https://serenity-js.org/handbook/test-runners/) and [reporting tools](https://serenity-js.org/handbook/reporting/).
- **TypeScript-first design** with strong typing for safer and more predictable test code.

## Installation

```bash
npm install --save-dev @serenity-js/core
````

See the [Serenity/JS Installation Guide](https://serenity-js.org/handbook/installation/).

## Quick Start

```ts
import { actorCalled } from '@serenity-js/core'

await actorCalled('Alice')
    .whoCan(
        // Add abilities
    )
    .attemptsTo(
        // Add tasks and interactions
    )
```
