+== iPeer v2 Technical Documentation ==
+
+=== rdAuth Components: ===
+rdAuth components monitors the current user’s information such as id, role, username, fullname.  To get the current user’s attribute, we can call:
+From View:              $rdAuth->id 
+From Controller:        $this->rdAuth->id
+=== Sys_Parameter Settings: ===
+System Parameters are loaded once the users has login successfully.  There are 2 core parameters that control the iPeer integration with UBC CWL:
+
+For General version:
+
+||Parameter Code||Parameter Value
+custom.login_control||ipeer
+custom.login_page_pathname||Leave it as empty
+
+For UBC CWL customization:
+
+Parameter Code
+Parameter Value
+custom.login_control
+UBC_CWL
+custom.login_page_pathname
+custom_ubc_cwl_login
+
+To check whether the iPeer is UBC CWL integrated or not:
+if (isset($this->rdAuth->customIntegrateCWL) && $this->rdAuth->customIntegrateCWL) {
+// ipeer is integrated with CWL
+}
+Get Sys_Parameter from iPeer:
+e.g. Get the parameter code ‘system.upload_dir’:
+                $uploadDir = $this->sysContainer->getParamByParamCode('system.upload_dir');
+                $uploadFile = APP.$uploadDir['parameter_value'] . $filename;
+
+
+Some useful functions:
+1.Get all accessible courses:
+        $courseList = $this->sysContainer->getMyCourseList();
+
+2.Get no. of members within a group:
+        $numMembers=$event['Event']['self_eval'] ? $this->GroupsMembers->findCount('group_id='.$groupId) :
+                                                                   $this->GroupsMembers->findCount('group_id='.$groupId) - 1;
+Caution: To upgrade CakePHP library for iPeer, please also look into the following files to change for iPeer customization:
+1.replace all thtml -> tpl.php, since iPeer use php extension instead of thtml
+2.change the controller.php in \cake\libs\controller 
+3.change html.php helper in \cake\libs\view\helpers
+4.change dbo_source.php in \cake\libs\model\datasources
+
+UBC CWL Integration:
+Instead of the Sys_Parameter setting from database, there are two files for CWL integration:
+ipeer_v2\app\controller\loginout_controller.php 
+ipeer_v2\app\views\loginout\custom_ubc_cwl_login.tpl.php
+
+Note: Remove all the following code when release the iPeer v2 to SourceForge. 
+
+From loginout_controller:
