+# Activiti Alfresco Content Service
+
+Get Alfresco Repository folder content based on a Repository account configured in Alfresco Process Services (APS). 
+It is possible to configure multiple Alfresco Repository accounts in APS (i.e. multiple Alfresco Servers).
+This service can also be used to link Alfresco content as related content in APS. 
+Content such as documents and other files can be attached to Process Instances 
+and Task Instances as related content.
+
+<aside class="warning">
+At the moment you must provide the `ActivitiAlfrescoContentService` class from your `NgModule` for it to work:
+```ts
+@NgModule({
+...
+  providers: [ActivitiAlfrescoContentService] 
+})
+```
+And also import it in the way shown below.
+</aside>
+
+## Importing
+
+```ts
+import { ActivitiAlfrescoContentService } from 'ng2-activiti-form/src/services/activiti-alfresco.service';
+
+export class SomePageComponent implements OnInit {
+
+ constructor(private contentService: ActivitiAlfrescoContentService) {
+   }
+```
+
+## Methods
+
+#### getAlfrescoNodes(accountId: string, folderId: string): Observable<[ExternalContent]>
+Get all the nodes under passed in folder node ID (e.g. 3062d73b-fe47-4040-89d2-79efae63869c) for passed in 
+Alfresco Repository account ID as configured in APS: 
+
+```ts
+export class SomePageComponent implements OnInit {
+ 
+  ngOnInit() {
+    const alfRepoAccountId = 'alfresco-2';
+    const folderNodeId = '3062d73b-fe47-4040-89d2-79efae63869c';
+    this.contentService.getAlfrescoNodes(alfRepoAccountId, folderNodeId).subscribe( nodes => {
+      console.log('Nodes: ', nodes);
+      }, error => {
+        console.log('Error: ', error);
+      });
+  }
+```
+
+In the above sample code the `alfRepoAccountId` points to an Alfresco Repository configuration in APS with ID `alfresco-2`.
+The `folderNodeId` needs to identify a folder node ID in the Alfresco Repository identified by the `alfRepoAccountId`.
+
+The response contained in `nodes` is an array with properties for each object like in this sample:
+
+```
+0:
+    folder: false
+    id: "2223d3c2-0709-4dd7-a79b-c45571901889;1.0"
+    simpleType: "pdf"
+    title: "JLAN_Server_Installation_Guide.pdf"
+1:
+    folder: false
+    id: "900b4dc0-bfdc-4ec1-84dd-5f1f0a420066;1.0"
+    simpleType: "image"
+    title: "Screen Shot 2017-09-21 at 15.44.23.png"
+    
+2:
+    folder: true
+    id: "f7010382-7b4e-4a78-bb94-9de092439230"
+    simpleType: "folder"
+    title: "Event More Stuff"
+```
+
+#### linkAlfrescoNode(accountId: string, node: ExternalContent, siteId: string): Observable<ExternalContentLink>
+Link Alfresco content as related content in APS by passing in Alfresco node identifying the content, the Share site
+that contains the content, and the Alfresco Repository account ID as configured in APS:
+
+```ts
+export class SomePageComponent implements OnInit {
+ 
+  ngOnInit() {
+    const alfRepoAccountId = 'alfresco-2';
+    const siteId = 'sample-workspace'; 
+    const externalContentNode = {
+      id: 'da196918-1324-4e97-9d26-d28f1837a0b6',
+      simpleType: 'content',
+      title: 'simple.txt',
+      folder: false
+    }
+    this.contentService.linkAlfrescoNode(alfRepoAccountId, externalContentNode, siteId).subscribe(link => {
+        console.log('Link: ', link);
+     }, error => {
+        console.log('Error: ', error);
+     });
+  }
+```
+
+In the above sample code the `alfRepoAccountId` points to an Alfresco Repository configuration in APS with ID `alfresco-2`.
+The `siteId` identifies an Alfresco Share site in the Alfresco Repository where the content to be linked resides.
+You can get the ID for a Share site from the URL: `http://localhost:8080/share/page/site/<siteId>`.
+The `externalContentNode` identifies the content that should be set up as temporary related content in APS. The 
+`externalContentNode.id` points to an Alfresco node in the Share site specified with `siteId`.
+
+The response contained in `link` looks like in this sample:
+
+```
+link:
+    contentAvailable: true
+    created: Tue Nov 07 2017 13:18:48 GMT+0000 (GMT) {}
+    createdBy: {id: 1, firstName: null, lastName: "Administrator", email: "admin@app.activiti.com"}
+    id: 6006
+    link:true
+    mimeType: null
+    name: "simple.txt"
+    previewStatus: "queued"
+    relatedContent: false
+    simpleType: "content"
+    source: "alfresco-2"
+    sourceId: "da196918-1324-4e97-9d26-d28f1837a0b6@sample-workspace"
+    thumbnailStatus: "queued"
+```
