+If you are using a [Symfony](https://symfony.com/) project, you can use the provider as a Symfony [bundle](https://symfony.com/doc/current/bundles.html).

+return [
+    ...
++  Ariga\AtlasDoctrineBundle::class => ['all' => true],
+];
+
+```
+
+Then in your project directory, create a new file named `atlas.hcl` with the following contents:
+
+```hcl
+data "external_schema" "doctrine" {
+  program = [
+    "php",
+    "bin/console", 
+    "atlas:dump-sql"
+  ]
+}

+  dev = "docker://mysql/8/dev"
+  migration {
