+
+AMLL's pure JS core component framework, including lyric display components and background components and other reusable components.
+
+Everything here is UI framework-independent, so it can be indirectly referenced under various dynamic page frameworks.
+
+Or if you need to use component bindings, there's a [React binding version](../react/README.md) and a [Vue binding version](../vue/README.md)
+
+## Features
+
+- Pure frontend rendering for lyrics and background
+- Word-level timed lyrics with translation and romanization
+- Multi-line, duet, and background line support
+- Style customization via CSS variables
+
+## Installation
+
+Install the required dependencies (if the dependencies listed below are not installed, you need to install them yourself):
+```bash
+npm install @pixi/app @pixi/core @pixi/display @pixi/filter-blur @pixi/filter-bulge-pinch @pixi/filter-color-matrix @pixi/sprite # using npm
+yarn add @pixi/app @pixi/core @pixi/display @pixi/filter-blur @pixi/filter-bulge-pinch @pixi/filter-color-matrix @pixi/sprite # using yarn
+```
+
+Install the framework:
+```bash
+npm install @applemusic-like-lyrics/core # using npm
+yarn add @applemusic-like-lyrics/core # using yarn
+```
+
+## Usage Summary
+
+For detailed API documentation, please refer to [./docs/modules.md](./docs/modules.md)
+
+A test program can be found in [../playground/core/src/test.ts](../playground/core/src/test.ts).
+
+```typescript
+import { LyricPlayer } from "@applemusic-like-lyrics/core";
+import "@applemusic-like-lyrics/core/style.css"; // Import required styles
+
+const player = new LyricPlayer(); // Create a lyric player component
+document.body.appendChild(player.getElement()); // Add the component's element to the page
+player.setLyricLines([]) // Set lyrics
+player.setCurrentTime(0) // Set current playback time (needs to be called every frame)
+player.update(0) // Update lyric component animation (needs to be called every frame)
+```
+
+The lyrics set through `LyricPlayer.setLyricLines` is a `LyricLine[]` parameter. For details, please refer to the code in [./src/interfaces.ts](./src/interfaces.ts).
+
+## Data Model
+
+Lyrics input is `LyricLine[]`, with each line containing:
+
+- `words`: timed word array, each word includes `startTime` / `endTime` / `word`, with optional `romanWord`, `ruby`, and `obscene`
+- `translatedLyric`: translation text
+- `romanLyric`: romanization text
+- `startTime` / `endTime`: line timestamps
+- `isBG` / `isDuet`: background and duet flags
+
+## Styling
+
+The main styles are provided by `@applemusic-like-lyrics/core/style.css`. Common overrides are via CSS variables:
+
+```css
+.amll-lyric-player {
+  --amll-lp-color: #ffffff;
+  --amll-lp-bg-color: rgba(0, 0, 0, 0.35);
+}
+```
+
+## Development
