-Library for database migrations
+
+Breyta is a **library** for database migrations. There are a lot of applications for database migrations but no
+actual library (without any user interface).
+
+## Trivia
+
+I created this library after trying ruckusing-migrations. It's the only one that does not require any additional library
+to provide a user interface and is mentioned in awesome-php. Unfortunately it seems to be not actively developed and
+maintained. Also I'm missing some functionality and it is very old, not using PSR-2/4 and namespaces.
+
+The name for this library comes again from the Icelandic language and means "to change".
+
+## Concept
+
+* A migration is a set of database statements
+* A migration has to run in a transaction
+* Logging is important and goes to the migration table
+* No code generating from this library (pure SQL)
+* No user interface (API only)
+* Generate fancy output and support progress bars
+
+## Installation
+
+We only support and suggest using composer - everything else on your own risk.
+
+```console
+$ composer require tflori/breyta
+```
+
+## Usage
+
+> This might change in the next days till version 1.
+
+Migration Script:
+
+```php
+<?php
+
+namespace Breyta\Migrations;
+
+use Breyta\AbstractMigration;
+
+class CreateUsersTable extends AbstractMigration
+{
+    public function up()
+    {
+        $this->exec('CREATE TABLE "users" (
+            "id" bigserial,
+            "name" character varying (255) NOT NULL,
+            PRIMARY KEY ("id")
+        )');
+    }
+
+    public function down()
+    {
+        $this->exec('DROP TABLE "users"');
+    }
+}
+```
+
+Control structure:
+
+```php
+
+namespace App\Cli\Commands;
+
+class MigrateCommand extends AbstractCommand
+{
+    /**
+     * Your database connection
+     * @var PDO
+     */
+    protected $db;
+
+    public function handle()
+    {
+        $breyta = new Breyta\Migrations($this->db, '/path/to/migrations');
+        $breyta->migrate(function ($message) {
+            $this->info($message); // how ever you output messages
+        });
+
+        $this->info($breyta->status());
+    }
+}
