Based on Yii2 Basic Project Template, used to test my experiments with AdminLTE

  assets/             contains assets definition
  commands/           contains console commands (controllers)
  components/         contains the template customized components

  models/             contains model classes
  runtime/            contains files generated during runtime
  tests/              contains various tests for the basic application
  vendor/             contains dependent 3rd-party packages
  views/              contains view files for the Web application
  web/                contains the entry script and Web resources
  widgets/            contains the widgets used by this template

The minimum requirement by this project template that your Web server supports PHP 5.4.0.

If you do not have Composer, you may install it by following the instructions at getcomposer.org.

You can then install this project template using the following command:

php composer.phar global require "fxp/composer-asset-plugin:~1.0.3"
php composer.phar create-project --prefer-dist --stability=dev machour/yii2-adminlte-demo adminlte

Now you should be able to access the application through the following URL, assuming adminlte is the directory directly under the Web root.

http://localhost/adminlte/web/

This template use several libraries in order to mimic AdminLTE behavior, here's a list:

Application level:

• dmstr/yii2-adminlte-asset

• ekaragodin/yii2-bootstrap-slider
• yii2mod/yii2-ion-slider

charts/chartjs.html

• 2amigos/yii2-chartjs-widget

charts/flot.html

• machour/yii2-jquery-flot

charts/inline.html

• machour/yii2-sparkline

Add these pages :

• index.html
• layout/top-nav.html
• layout/boxed.html
• layout/fixed.html
• layout/collapsed-sidebar.html
• widgets.html
• charts/morris.html
• charts/inline.html
• UI/icons.html
• UI/buttons.html
• forms/general.html
• forms/advanced.html
• forms/editors.html
• tables/simple.html
• tables/data.html

• mailbox.html
• examples/invoice.html
• examples/profile.html
• examples/login.html
• examples/register.html
• examples/lockscreen.html

• examples/blank.html

.. and finish the following pages :

• index2.html
• UI/general.html
• UI/timeline.html
• charts/flot.html (the live chart + labels for donut)

Edit the file config/db.php with real data, for example:

return [
    'class' => 'yii\db\Connection',
    'dsn' => 'mysql:host=localhost;dbname=yii2basic',
    'username' => 'root',
    'password' => '1234',
    'charset' => 'utf8',
];

NOTE: Yii won't create the database for you, this has to be done manually before you can access it.

Also check and edit the other files in the config/ directory to customize your application.
