+## Authentication 
+
+Basic auth integration is implemeted via an `auth` section.  An auth provider can be configured using the `provider` section with the given type.  Currently the only provider supported is `proxy`, where the users identification and group membership are passed via HTTP Request headers (in plaintext).  The expectation is that the application will be accessed only via an authenticating proxy (i.e treafik ).  
+
+The group and user headers are both configurable like so: 
+```yaml 
+auth: 
+  provider:
+    type: proxy 
+    groupHeader: "X-group-header" 
+    userHeader: "X-user-header" 
+```
+
+Auth can be configured on the service, bookmark, and widget level using the `allowUsers` and `allowGroups` list.  
+
+```yaml
+- Example Servie: 
+  allowGroups: 
+    - Group1
+    - Group2
+    - Group3
+  allowUsers: 
+    - User1
+    - User2
+    - User3
+```
+
+Auth for groups can be set in the `groups` under `auth`. 
+
+```yaml 
+auth: 
+  groups: 
+    My Service Group: 
+      allowGroups: ['Group1', 'Group2']
+```
