-# svelte app
+# rrweb-player
 
-This is a project template for [Svelte](https://svelte.technology) apps. It lives at https://github.com/sveltejs/template.
+Since rrweb's replayer only provides a basic UI, you can choose rrweb-replayer which is based on rrweb's public APIs but has a feature-rich replayer UI.
 
-To create a new project based on this template using [degit](https://github.com/Rich-Harris/degit):
+## How is this different from `rrweb.Replayer`?
 
-```bash
+rrweb-player uses rrweb's Replayer under the hood, but as Replayer doesn't include any UI for controls, rrweb-player adds those.
-npm install -g degit # you only need to do this once
 
-degit sveltejs/template svelte-app
+## Installation
-cd svelte-app
+
+rrweb-player can also be included with `<script>`：
+
+```html
+<link
+  rel="stylesheet"
+  href="https://cdn.jsdelivr.net/npm/rrweb-player@latest/dist/style.css"
+/>
+<script src="https://cdn.jsdelivr.net/npm/rrweb-player@latest/dist/index.js"></script>
 ```
 
-_Note that you will need to have [Node.js](https://nodejs.org) installed._
+Or installed by using NPM：
 
-## Get started
+```shell
-
+npm install --save rrweb-player
-Install the dependencies...
-
-```bash
-cd svelte-app
-npm install
 ```
 
-...then start [Rollup](https://rollupjs.org):
+```js
-
+import rrwebPlayer from 'rrweb-player';
-```bash
+import 'rrweb-player/dist/style.css';
-npm run dev
 ```
 
-Navigate to [localhost:5000](http://localhost:5000). You should see your app running. Edit a component file in `src`, save it, and reload the page to see your changes.
+## Usage
 
-## Deploying to the web
+```js

+## methods on the rrwebPlayer component
+
+```ts

-As an alternative, use the [Now desktop client](https://zeit.co/download) and simply drag the unzipped project folder to the taskbar icon.
+```ts
-
+addEvent(event: eventWithTime): void;
-### With [surge](https://surge.sh/)
-
-Install `surge` if you haven't already:

+```ts
-
+getMetaData() => {
-```bash
+    startTime: number;
-npm run build

-surge public
+    totalTime: number;
+}

+```
+
+Toggles between play/pause
+
+```ts
+toggle();

+
+Sets speed of player
+
+```ts
+setSpeed(speed: number)

+
+```ts
+playRange(
