-External Link Providers
-=======================
-
-This functionality allows you to link a task to additional items stored on another system.
-
-For example, you can link a task to:
-
-- Traditional web page
-- Attachment (PDF documents stored on the web, archive...)
-- Any ticketing system (bug tracker, customer support ticket...)
-
-Each item has a type, a URL, a dependency type and a title.
-
-By default, Kanboard includes two kinds of providers:
-
-- Web Link: You copy and paste a link and Kanboard will fetch the page title automatically
-- Attachment: Link to anything that is not a web page
-
-Workflow
---------
-
-1. The end-user copy and paste the URL to the form and submit
-2. If the link type is "auto", Kanboard will loop through all providers registered until there is a match
-3. Then, the link provider returns a object that implements the interface `ExternalLinkInterface`
-4. A form is shown to the user with all pre-filled data before to save the link
-
-Interfaces
-----------
-
-To implement a new link provider from a plugin, you need to create 2 classes that implement those interfaces:
-
-- `Kanboard\Core\ExternalLink\ExternalLinkProviderInterface`
-- `Kanboard\Core\ExternalLink\ExternalLinkInterface`
-
-### ExternalLinkProviderInterface
-
-| Method                     | Usage                                                           |
-|----------------------------|-----------------------------------------------------------------|
-| `getName()`                | Get provider name (label)                                       |
-| `getType()`                | Get link type (will be saved in the database)                   |
-| `getDependencies()`        | Get a dictionary of supported dependency types by the provider  |
-| `setUserTextInput($input)` | Set text entered by the user                                    |
-| `match()`                  | Return true if the provider can parse correctly the user input  |
-| `getLink()`                | Get the link found with the properties                          |
-
-### ExternalLinkInterface
-
-| Method            | Usage            |
-|-------------------|------------------|
-| `getTitle()`      | Get link title   |
-| `getUrl()`        | Get link URL     |
-| `setUrl($url)`    | Set link URL     |
-
-Register a new link provider
-----------------------------
-
-In your `Plugin.php`, just call the method `register()` from the object `ExternalLinkManager`:
-
-```php
-<?php
-
-namespace Kanboard\Plugin\MyExternalLink;
-
-use Kanboard\Core\Plugin\Base;
-
-class Plugin extends Base
-{
-    public function initialize()
-    {
-        $this->externalLinkManager->register(new MyLinkProvider());
-    }
-}
-```
-
-Examples
---------
-
-- Kanboard includes the default providers "WebLink" and "Attachment"
