+Twig Gettext Extractor [![Build Status](https://secure.travis-ci.org/umpirsky/Twig-Gettext-Extractor.png?branch=master)](http://travis-ci.org/umpirsky/Twig-Gettext-Extractor)
+======================
+
+The Twig Gettext Extractor is [Poedit](http://www.poedit.net/download.php)
+friendly tool which extracts translations from twig templates.
+
+## Installation
+
+The recommended way to install Twig Gettext Extractor is through
+[composer](http://getcomposer.org).
+
+```json
+{
+    "require": {
+        "umpirsky/twig-gettext-extractor": "1.1.*"
+    }
+}
+```
+
+## Setup
+
+By default, Poedit does not have the ability to parse Twig templates.
+This can be resolved by adding an additional parser (Edit > Preferences > Parsers)
+with the following options:
+
+- Language: `Twig`
+- List of extensions: `*.twig`
+- Invocation:
+    - Parser command: `<project>/vendor/bin/twig-gettext-extractor --sort-output --force-po -o %o %C %K -L PHP --files %F`
+    - An item in keyword list: `-k%k`
+    - An item in input file list: `%f`
+    - Source code charset: `--from-code=%c`
+
+<img src="http://i.imgur.com/f9px2.png" />
+
+Now you can update your catalog and Poedit will synchronize it with your twig
+templates.
+
+## Tests
+
+To run the test suite, you need [composer](http://getcomposer.org) and
+[PHPUnit](https://github.com/sebastianbergmann/phpunit).
+
+    $ composer install --dev
+    $ phpunit
+
