+Using as Phalcon Framework Task
+===============================
+
+Migrations come with predefined Phalcon CLI Task. Task uses these two services:
+
+* **config** (`\Phalcon\Config`) with key `migrationsDir`. See example config.php below.
+* **driver** (`\Nextras\Migrations\IDriver`). See example in cli.php below.
+
+Service `driver` needs `\Nextras\Migrations\Bridges\Phalcon\PhalconAdapter` as argument. Therefore you will probably need to declare other services (see cli.php) or create phalcon adapter inside **driver**'s lambda function.
+
+`config/config.php`

+Usage
+-----
+
+`php app/cli.php Nextras\\Migrations\\Bridges\\Phalcon\\Migrations main <action>[:<group>:<label>][:production]`
+
+Examples:
+* `php app/cli.php Nextras\\Migrations\\Bridges\\Phalcon\\Migrations main create:dummy-data:users`
+* `php app/cli.php Nextras\\Migrations\\Bridges\\Phalcon\\Migrations main cr:d:users`
+* `php app/cli.php Nextras\\Migrations\\Bridges\\Phalcon\\Migrations main reset`
+* `php app/cli.php Nextras\\Migrations\\Bridges\\Phalcon\\Migrations main co:production`
+
+**Actions:**
+* create
+  * Can be aliased as "cr".
+  * Creates empty sql file named YYYY-MM-DD-HHMMSS-label.sql.
+  * E.g. 2015-03-16-170342-users.sql.
+  * <label> is mandatory for "create" action.
+* continue
+  * Can be aliased as "co".
+  * Migrates not migrated sql files only.
+  * Optional flag "production" (if present all dummy-data files are skipped).
+* reset
+  * Can be aliased as "re".
+  * Drop whole database and then migrates all sql files.
+  * Optional flag "production" (if present all dummy-data files are skipped).
+
+**Groups:**
+* basic-data
+  * Can be aliased as "b".
+  * Data for both development and production.
+* dummy-data
+  * Can be aliased as "d".
+  * Data for development on localhost.
+* structures
+  * Can be aliased as "s".
+  * Creates, alter tables, etc.
+
+**Label:**
+* For "create" action only. Should be some brief name for sql file contents.
+
+**Production:**
+* For "continue" and "reset" actions only.
+* If present all dummy-data files are skipped.
