 # Nextlint
 
-Nextlint is a WYSIWYG (What You See Is What You Get) editor built using the "@tiptap" library and developed with Svelte. It provides a user-friendly interface for editing and formatting text, allowing users to create rich content effortlessly.
+Rich text editor (WYSIWYG) written in Svelte, using [MeltUI](https://melt-ui.com/) headless UI and [tailwindcss](https://tailwindcss.com/) CSS framework.
 
-- 💻 **Easy-to-use:** The editor provides a simple and intuitive interface, making it easy for users to create and edit content without any technical knowledge.
-- ✍️ **Rich Text Editing:** Users can format text using various styles such as bold, italic, underline, headings, lists, and more.
-- 🧱 **Extensible:** You can extend the editor's functionality by adding or creating custom extensions, allowing you to integrate additional features or customize the behavior of the editor.
-- 🧠 **Integrate openAI,GPT functionality:** Unlocking the Power of Creative and Swift Writing with OpenAI and GPT Support.
+Built on top of [tiptap](https://tiptap.dev/) editor(headless editor) and [prosemirror](https://prosemirror.net/). Easy to use, develop and maintain. A prompt engine that helps to integrate with any AI API, and enhance the writing experience. 
+
+Dark/Light theme is supported and customizable. 
+
+## Getting started
+
+### Install
+
+```sh
+//npm
+npm install @nextlint/svelte
+
+//yarn
+yarn add @nextlint/svelte
+
+//pnmp
+npm add @nextlint/svelte
+```
+
+### Setup
+Nexltint editor uses headless svelte components from MeltUI and styles it with tailwindcss. The theme tokens are inherited from [Svelte Shadcn](https://www.shadcn-svelte.com/docs/theming).
+
+If you already have shadcn setup in your project then you can skip this part.
+
+
+#### 1. Install tailwindcss and postcss:
+
+```sh
+pnpm add -D tailwindcss postcss autoprefixer sass
+npx tailwindcss init -p
+```
+Now `tailwind.config.js` and `postcss.config.js` are created
+
+#### 2. Configure tailwind.config.js:
+
+```js
+
+// more detail at https://www.shadcn-svelte.com/docs/installation/manual
+
+/** @type {import('tailwindcss').Config} */
+module.exports = {
+  content: [
+    "./src/**/*.{svelte,js}",
+    "./node_modules/@nextlint/svelte/dist/**/*.{svelte,ts}"
+  ],
+  theme: {
+    extend: {
+      colors: {
+        border: "hsl(var(--border) / <alpha-value>)",
+        input: "hsl(var(--input) / <alpha-value>)",
+        ring: "hsl(var(--ring) / <alpha-value>)",
+        background: "hsl(var(--background) / <alpha-value>)",
+        foreground: "hsl(var(--foreground) / <alpha-value>)",
+        primary: {
+          DEFAULT: "hsl(var(--primary) / <alpha-value>)",
+          foreground: "hsl(var(--primary-foreground) / <alpha-value>)",
+        },
+        secondary: {
+          DEFAULT: "hsl(var(--secondary) / <alpha-value>)",
+          foreground: "hsl(var(--secondary-foreground) / <alpha-value>)",
+        },
+        destructive: {
+          DEFAULT: "hsl(var(--destructive) / <alpha-value>)",
+          foreground: "hsl(var(--destructive-foreground) / <alpha-value>)",
+        },
+        muted: {
+          DEFAULT: "hsl(var(--muted) / <alpha-value>)",
+          foreground: "hsl(var(--muted-foreground) / <alpha-value>)",
+        },
+        accent: {
+          DEFAULT: "hsl(var(--accent) / <alpha-value>)",
+          foreground: "hsl(var(--accent-foreground) / <alpha-value>)",
+        },
+        popover: {
+          DEFAULT: "hsl(var(--popover) / <alpha-value>)",
+          foreground: "hsl(var(--popover-foreground) / <alpha-value>)",
+        },
+        card: {
+          DEFAULT: "hsl(var(--card) / <alpha-value>)",
+          foreground: "hsl(var(--card-foreground) / <alpha-value>)",
+        },
+      },
+      borderRadius: {
+        lg: "var(--radius)",
+        md: "calc(var(--radius) - 2px)",
+        sm: "calc(var(--radius) - 4px)",
+      },
+      fontFamily: {
+        sans: ["Inter"],
+      },
+    },
+  },
+  plugins: [],
+}
+```
+Theme can customize via css tokens. The default token is located at [EditorTheme.scss](https://github.com/sveltor/nextlint/blob/main/packages/svelte/src/lib/EditorTheme.scss).
+
+### Usage:
+To use the default theme, you need to wrap your `SvelteEditor` component with `ThemeTheme`:
+```svelte
+<script lang="ts">
+  import { SvelteEditor, EditorTheme } from "@nextlint/svelte" 
+</script>
+  
+<div class='editor'>
+  <EditorTheme>
+    <SvelteEditor 
+      content=""
+      placeholder="Start editing..."
+    />
+  </EditorTheme>
+</div>
+```
+
+The `EditorTheme` basicaly just import the default theme we define in `EditorTheme.scss`:
+
+```svelte
+
+//EditorTheme.svelte
+
+<script lang="ts">
+  import './EditorTheme.scss';
+</script>
+
+<slot />
+```
+
+Nexltint editor uses `nextlint/core`, which is a headless editor with [existing](https://github.com/sveltor/nextlint/blob/main/packages/core/src/editor/starterKit.ts#L57) plugins installed, can be used in any UI framework, compatible with tiptap and prosemirror plugins system.
+
+Nextlint Svelte itself has some [plugins](https://github.com/sveltor/nextlint/tree/main/packages/svelte/src/lib/plugins) completely written in Svelte and [configurable](https://github.com/sveltor/nextlint/blob/main/packages/svelte/src/lib/Editor.svelte#L2)
