 NiseLine is inspired by [LocalStack](https://github.com/localstack/localstack). Goal of this tool is to create a mock service for [LINE](https://line.me/ja/).
 
-## Setup
+## Getting Started
 
-### Docker
+Launch NiseLine server.
+
+```bash
+docker run -d -p 3000:3000 dyoshikawa/niseline:latest
+```
+
+And install NiseLiff SDK.
+
+```bash
+npm i @niseline/niseliff
+```
+
+Use NiseLiff sdk in your client app!
+
+```tsx
+import { buildNiseLiff } from '@niseline/niseliff'
+import React from 'react'
+import ReactDOM from 'react-dom'
+
+const niseliff = buildNiseLiff()
+
+niseliff
+  .init({
+    liffId: 'DEFAULT_LIFF_ID', // You can any value
+  })
+  .then(() => {
+    ReactDOM.render(
+      <React.StrictMode>Your client app</React.StrictMode>,
+      document.getElementById('root')
+    )
+  })
+```
+
+## NiseLiff SDK
+
+### Setup
+
+```bash
+npm i @niseline/niseliff
+```
+
+### Usage
+
+```tsx
+import { buildNiseLiff } from '@niseline/niseliff'
+import React from 'react'
+import ReactDOM from 'react-dom'
+
+const niseliff = buildNiseLiff()
+
+niseliff
