### Introduction

## What is AdminLTE?

AdminLTE is a free, MIT-licensed admin dashboard template built on Bootstrap 5.3.8 with vanilla TypeScript (no jQuery). It ships responsive layouts, a sidebar navigation system, light/dark/auto color mode, RTL support, and a growing catalog of demo pages — calendar, kanban, chat, file manager, invoice, profile, settings, and more.

It’s a template, not a component library. You drop the markup into your own project (or framework templates) and customize the parts you need. Bootstrap 5 handles the components; AdminLTE provides the application shell.

If you’ve never used AdminLTE before, start with Getting Started — it walks through a working dashboard in ten minutes.

## Installation paths

Pick the path that matches how you’ll actually use AdminLTE:

Path | Best for | Setup time
--- | --- | ---
CDN | Prototyping, demos, simple sites | 1 minute
npm + bundler | Production apps, framework projects (Laravel, Symfony, Rails) | 5 minutes
Build from source | You need to customize SCSS variables, sidebar width, breakpoints | 10 minutes
Composer | PHP projects that prefer Packagist over npm | 2 minutes

### CDN — fastest path

Drop these four CSS tags into `<head>` and four script tags before `</body>`. No install, no build step:

    <!-- In <head> -->
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap-icons@1.13.1/font/bootstrap-icons.min.css" />
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/overlayscrollbars@2.11.0/styles/overlayscrollbars.min.css" />
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/admin-lte@4.0.0/dist/css/adminlte.min.css" />

    <!-- Before </body> -->
    <script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.11.8/dist/umd/popper.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.8/dist/js/bootstrap.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/overlayscrollbars@2.11.0/browser/overlayscrollbars.browser.es6.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/admin-lte@4.0.0/dist/js/adminlte.min.js"></script>

Then copy any demo page HTML into your own file. See Getting Started for the minimum-viable layout.

### npm + bundler

Requires Node.js 18+ and a bundler (Vite, Webpack, Rollup, esbuild, etc.).

    npm install admin-lte@4.0.0

Then import the CSS and JS in your app entry point:

    // CSS
    import "admin-lte/dist/css/adminlte.min.css"
    // Plus Bootstrap and dependency CSS
    import "bootstrap-icons/font/bootstrap-icons.css"
    import "overlayscrollbars/styles/overlayscrollbars.css"

    // JS
    import "bootstrap"
    import "admin-lte"

Yarn and pnpm work the same way — substitute `yarn add` or `pnpm add` for the install.

### Build from source

If you want to customize SCSS variables (sidebar width, breakpoints, brand colours), clone the repo and build locally:

    git clone https://github.com/ColorlibHQ/AdminLTE.git
    cd AdminLTE
    npm install
    npm run dev          # dev server with hot-reload at localhost:3000
    npm run production   # one-off production build (clean + lint + compile)

The compiled output lands in `dist/`. Edit `src/scss/_variables.scss` or `src/scss/_bootstrap-variables.scss`, then rerun the build. See Customization & Theming for which variables matter.

### Composer

For PHP projects:

    composer require "almasaeed2010/adminlte=4.0.0"

The package is published from the same source tree — you get the `dist/` folder ready to serve.

## Prerequisites

| Minimum | Recommended
--- | --- | ---
Bootstrap | 5.3.0 | 5.3.8 (pinned in `package.json`)
Node.js | 18 LTS | 22 LTS (used by CI)
Browser | Modern evergreen | Latest stable Chrome/Firefox/Safari/Edge

AdminLTE 4 does not support Internet Explorer. If you need IE11, stay on AdminLTE 3 or earlier.

## Where to next

- Getting Started — a working dashboard in 10 minutes
- Layout — the app-wrapper structure and responsive options
- Customization — change colours, sidebar width, spacing
- Migration from v3 — upgrading an existing AdminLTE 3 project
