+# Node Public file Share Directive
+
+Create and manage public shared links for files
+
+![adf-share](../docassets/images/share-directive.png)
+
+This dialog will generate a link that will be formed as "baseShareUrl + sharedId".
+For example if you set the input parameter [baseShareUrl]="http://localhos:8080/myrouteForShareFile/", 
+the directive will ask to the Content service to generate a sharedId for the file. This will end up with a url link like :
+
+http://localhos:8080/myrouteForShareFile/NEW_GENERATED_SHAREID
+
+After you will need to implement in your app a logic that throught the router get the NEW_GENERATED_SHAREID and pass it to the ***adf-viewer***
+
+```html
+<adf-viewer
+    [sharedLinkId]="NEW_GENERATED_SHAREID"
+    [allowGoBack]="false">
+</adf-viewer>
+```
+
+## Basic Usage
+
+```html
+<adf-toolbar>
+    <button mat-icon-button
+            [baseShareUrl]="http://localhos:8080/myrouteForShareFile/"
+            [adf-share]="documentList.selection[0]">
+            <mat-icon>share</mat-icon>
+    </button>
+</adf-toolbar>
+
+<adf-document-list #documentList ...>
+ ...
+</adf-document-list>
+```
