 Advanced application template
 =============================
 
+This template is for large projects developed in teams where backend is divided from frontend, application is deployed
+to multiple servers etc. This application template also goes a bit further regarding features and provides essential
+database, signup and password restore out of the box.
+
+Directory structure
+-------------------
+
+The root directory contains the following subdirectories:
+
+- `backend` - backend web application.
+- `common` - files common to all applications.
+- `console` - console application.
+- `environments` - environment configs.
+- `frontend` - frontend web application.
+
+Root directory contains a set of files.
+
+- `.gitignore` contains a list of directories ignored by git version system. If you need something never get to your source
+  code repository, add it there.
+- `composer.json` - Composer config described in detail below.
+- `init` - initialization script described in "Composer config described in detail below".
+- `init.bat` - same for Windows.
+- `LICENSE.md` - license info. Put your project license there. Especially when opensourcing.
+- `README.md` - basic info about installing template. Consider replacing it with information about your project and its
+  installation.
+- `requirements.php` - Yii requirements checker.
+- `yii` - console application bootstrap.
+- `yii.bat` - same for Windows.
+
+Applications
+------------
+
+There are three applications in advanced template: frontend, backend and console. Frontend is typically what is presented
+to end user, the project itself. Backend is admin panel, analytics and such functionality. Console is typically used for
+cron jobs and low-level server management. Also it's used during application deployment and handles migrations and assets.
+
+There's also a `common` directory that contains files used by more than one application. For example, `User` model.
+
+frontend and backend are both web applications and both contain `web` directory. That's the webroot you should point your
+webserver to.
+
+Configuration and environments
+------------------------------
+
+
+
+Configuring Composer
+--------------------
+
+After application template is installed it's a good idea to adjust defaul `composer.json` that can be found in the root
+directory:
+
+```javascript
+{
+	"name": "yiisoft/yii2-app-advanced",
+	"description": "Yii 2 Advanced Application Template",
+	"keywords": ["yii", "framework", "advanced", "application template"],
+	"homepage": "http://www.yiiframework.com/",
+	"type": "project",
+	"license": "BSD-3-Clause",
+	"support": {
+		"issues": "https://github.com/yiisoft/yii2/issues?state=open",
+		"forum": "http://www.yiiframework.com/forum/",
+		"wiki": "http://www.yiiframework.com/wiki/",
+		"irc": "irc://irc.freenode.net/yii",
+		"source": "https://github.com/yiisoft/yii2"
+	},
+	"minimum-stability": "dev",
+	"require": {
+		"php": ">=5.3.0",
+		"yiisoft/yii2": "dev-master",
+		"yiisoft/yii2-composer": "dev-master"
+	},
+	"scripts": {
+		"post-create-project-cmd": [
+			"yii\\composer\\InstallHandler::setPermissions"
+		]
+	},
+	"extra": {
+		"yii-install-writable": [
+			"backend/runtime",
+			"backend/web/assets",
+
+			"console/runtime",
+			"console/migrations",
+
+			"frontend/runtime",
+			"frontend/web/assets"
+		]
+	}
+}
+
+```
+
+First we're updating basic information. Change `name`, `description`, `keywords`, `homepage` and `support` to match
+your project.
+
+Now the interesting part. You can add more packages your application needs to `require` section.
+For example, to use markdown helper you need to add `michelf/php-markdown`. All these packages are coming from
+[packagist.org](https://packagist.org/) so feel free to browse the website for useful code.
+
+After your `composer.json` is changed you can run `php composer.phar update`, wait till packages are downloaded and
+installed and then just use them. Autoloading of classes will be handled automatically.
