-### Minimal configuration
-
-```typescript
-export default async () => {
-  return {
-    defaultTemplate: 'typescript',
-    outDir: './.xmigrate',
-    typescript: true,
-    mongodb: {
-      url: 'mongodb://localhost:27017',

-        useNewUrlParser: true,
-      },
-    },
-  };
-};
-```

-### Performance tests
-
-Running 600 `migrations` takes less than 15 seconds in TypeScript compiled right down to Javascript ES5.
