+Basic usage
+===========
+
+## Install Fenom
+
+### Composer
+
+Add package Fenom in your require-list in `composer.json`:
+```json
+{
+    "require": {
+        "fenom/fenom": "2.*"
+    }
+}
+```
+and update project's dependencies: `composer update`.
+
+### Custom loader
+
+Clone Fenom to any directory: `git clone https://github.com/bzick/fenom.git`. Recommended use latest tag.
+Fenom use [psr-0](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md#autoloading-standard) autoloading standard. Therefore you can
+* use `psr-0` format in your project loader for loading Fenom's classes
+* or register Fenom's autoloader: ```php
+Fenom::registerAutoload();
+```
+For loading itself.
+
+Also you can use this autoloader for loading any library with `psr-0` file naming:
+```php
+Fenom::registerAutoload(PROJECT_DIR."/src");
+```
+
+## Setup Fenom
+
+Create an object via factory method
+```php
+$fenom = Fenom::factory('/path/to/templates', '/path/to/compiled/template', $options);
+```
+
+Create an object via `new` operator
+```php
+$fenom = new Fenom(new Provider('/path/to/templates'));
+$fenom->setCompileDir('/path/to/template/cache');
+$fenom->setOptions($options);
+```
+
+* `/path/to/templates` — directory, where stores your templates.
+* `/path/to/template/cache` — directory, where stores compiled templates in PHP files.
+* `$options` - bit-mask or array of [Fenom settings](./docs/settings.md).
+
+### Use Fenom
+
+Output template
+```php
+$fenom->display("template/name.tpl", $vars);
+```
+
+Get the result of rendering the template
+```php
+$result = $fenom->fetch("template/name.tpl", $vars);
+```
+
+Create the pipeline of rendering into callback
+```php
+$fenom->pipe(
+    "template/sitemap.tpl",
+    $vars,
+    $callback = [new SplFileObject("/tmp/sitemap.xml", "w"), "fwrite"], // pipe to file /tmp/sitemap.xml
+    $chunk_size = 1e6 // chunk size for callback
+);

+Syntax
-===========
+======
 
-Fenom implement [Smarty](http://www.smarty.net/) syntax with some improvements
+Fenom implements [Smarty](http://www.smarty.net/) syntax with some improvements.
+All Fenom tags enclosed in the delimiters `{` and `}`, for example `{var $five = 5}`.
+If you wanna leave delimiters as is in the template use [special statements or tags](#ignoring-delimiters).
+
+*Note*
+Fenom implements [Smarty](http://www.smarty.net/) syntax but not implements Smarty tags, however, some tags very similar.
+But not so bad, Fenom has the [extras](https://github.com/bzick/fenom-extra) that make Fenom like Smarty.
 
 ## Variable
 
-### Use variables
+Variables in Fenom can be either displayed directly or used as arguments for functions, attributes and modifiers,
+inside conditional expressions, etc.
+
+### Example variables
+
+Next example uses simple variables `$user_id` ans `$user_name`
+```smarty
+<div class="user">Hello, <a href="/users/{$user_id}">{$user_name}</a>.</div>
+```
+
+Example outputs next HTML code:
+```html
+<div class="user">Hello, <a href="/users/17">Bzick</a>.</div>
+```
+
+Переменные могут быть массивом. В этом случае обращение по ключу происходит через опертор `.` или, как в PHP, через операторы `[` и `]`
+```smarty
+<div class="user">Hello, <a href="/users/{$user.id}">{$user.name}</a>.</div>
+```
+
+`{$user.id}` and `{$user['id']}` are same.
+
+```smarty
+<div class="user">Hello, <a href="/users/{$user->id}">{$user->name}</a>.</div>
+```
+
+```smarty
+<div class="user">Hello, <a href="/users/{$user->getId()}">{$user->getName()}</a>.</div>
+```
+
+*Note*
+Be careful, Fenom do not checks existence of the method before invoke.
+To avoid the problem class of the object have to define method `__call`, which throws an exception etc.
+Also you may disable invoke method in [settings](./docs/settings.md).
+
+Multidimensional value support
+
+```smarty
+{$foo.bar.baz}
+{$foo.$bar.$baz}
+{$foo[4].baz}
+{$foo[4].$baz}
+{$foo.bar.baz[4]}
