+# Interface
+
+The package provides and interface `\Astrotomic\Translatable\Contracts\Translatable` which describes the public API. It could be that the trait defines more public methods but they aren't part of the defined public API and won't force a new major release if changed or removed.
+
+In addition to the interface we rely on the following methods which will, if changed or removed, also trigger a new major release.
+
+## protected Interface
+
+```php
+interface TranslatableProtected
+{
+    // detect if a given translation attribute value is empty or not
+    protected function isEmptyTranslatableAttribute(string $key, $value): bool;
+    
+    // save all attached translations
+    protected function saveTranslations(): bool;
+}
+```
