+   + out/         The module package to deploy. Generated by tools/release script.
+   + vendor/      Useful libraries. Generated by composer.
+```
+
+###Internationalization
+  Only .po files must be updated. Filename format is **githubembed-*LANGUAGE CODE*.po**, for example:  *githubembed-es_ES.po*
+
+  To generate .mo files use
+```shell
+  ./tools/generate_mo_files
+```
+
+###Deploy
+  Use *release* script to generate the plugin package
+```shell
+  ./tools/release
+```
+
+  The package files .zip and .tar.gz will be in *out/* directory
+
+###Recommended environment
+####Testing server
+1. Install and configure two english Wordpress sites running at http://localhost/sandbox/wordpress/simply/ and http://localhost/sandbox/wordpress/multisite/
+
+  If you prefer other location, change the *behat.yml* file.
+```yml
+  base_url: http://localhost/sandbox/wordpress
+```
+
+**Wordpress admin must be in english for BDD tests**
+
+2. Create a admin user named *test* which email *[email protected]* and password *testtest*. Set Administrator profile to this user.
+
+  If you prefer other other test user credentials, change the *features/bootstrap/FeatureContext.php*] file.
+```php
+  define('WORDPRESS_ADMIN_USER', 'test');
+  define('WORDPRESS_ADMIN_PASSWORD', 'testtest');
+```
+
+3. Configure the http://localhost/sandbox/wordpress/multisite/ as multisite, check the Codex for more info on this topic: [Create_A_Network](http://codex.wordpress.org/Create_A_Network)
+
+4. Create a blog named *test1* in http://localhost/sandbox/wordpress/multisite/test1/
+
+5. Link src project directory to your Wordperfect site plugins directory
+```shell
+  ln -s /home/developer/projects/wp-github-oembed/src/ /var/www/sandbox/wordpress/simply/wp-content/plugins/github-embed
+  ln -s /home/developer/projects/wp-github-oembed/src/ /var/www/sandbox/wordpress/multisite/wp-content/plugins/github-embed
+```
+
+
+####BDD
+Use [Composer](http://getcomposer.org/) to install [Behat](http://behat.org) and all necesary files.
+```shell
+  curl -s https://getcomposer.org/installer | php
+  ./composer.phar install
+```
+
+You can test the development environment configuration
+```shell
+	./bin/behat features/enviroment/
+```
+
+Run all tests
+```shell
+	./bin/behat
+```
+
+Run all tests for simply wordpress
+```shell
+	./bin/behat features/simply/
+```
+
+Run all tests for multisite wordpress
+```shell
+	./bin/behat features/multisite/
+```
