NEW Default link title for each link type

 Note that you also need to add a `has_one` relation on the `Link` model to match your `has_many` here. See [official docs about `has_many`](https://docs.silverstripe.org/en/developer_guides/model/relations/#has-many)
 
+### Default title for each link type
+
+By default, if the title for the link has not been set, then the default title will be used instead according to the type of link that is used. Default link is not stored in the database as link title. This value is used only when rendering page content. 
+This title is used by default. The developer can completely disable the use of the default title for all types of links or for each type separately.
+
+*app/_config/mylink.yml*
+```yml
+SilverStripe\LinkField\Models\Link:
+  use_default_title: false
+
+SilverStripe\LinkField\Models\PhoneLink:
+  use_default_title: false
+```
+
+The developer also can set his own default title value using an extension by using `updateDefaultLinkTitle` method for each link type class or by setting the `default_link_title` value in the configuration file.
+
+*app/_config/mylink.yml*
+```yml
+SilverStripe\LinkField\Models\Link:
+  use_default_title: true
+
+SilverStripe\LinkField\Models\PhoneLink:
+  default_link_title: 'My Phone Link'
+```
+
+*app/src/ExternalLinkExtension*
+```php
+<?php
+
+namespace App\Extensions;
+
+use SilverStripe\ORM\DataExtension;
+
+class ExternalLinkExtension extends DataExtension
+{
+  public function updateDefaultLinkTitle(&$defaultLinkTitle): void
+  {
+    $defaultLinkTitle = sprintf('External link: %s', $this->owner->ExternalUrl);
+  }
+}
+
+```

+## Migrating from Version `1.0.0` or `dev-master`
+
+Please be aware that in early versions of this module (and in untagged `dev-master`) there were no table names defined
+for our `Link` classes. These have now all been defined, which may mean that you need to rename your old tables, or
+migrate the data across.
+
+EG: `SilverStripe_LinkField_Models_Link` needs to be migrated to `LinkField_Link`.
