-By default the CMS ships with a couple of basic reports -
 
 ## Default Reports
 
-*  "Empty Pages" which will generate a list of pages without content 
-*  "Pages edited in the last 2 weeks" which will list all the pages edited in the last 2 weeks in order of most recently
-edited.
-*  "To Do" which displays all the ToDo notes you have added to each page and a link to the page. Note: This is in 2.2.2 and
-later
-*  Also the Ecommerce module provides 2 or 3 reports out of box. Such as All Products, Orders...
+By default the CMS ships with several basic reports:

+*  RedirectorPages pointing to deleted pages
+*  Pages with broken files
+*  Pages with broken links
+*  Broken links report
+*  Pages with no content

 ## Creating Custom Reports
 
-You can create reports for you own data quickly and easily. A general knowledge of SilverStripe's
-[Datamodel](/topics/datamodel) would help before you attempt this. 
+Custom reports can be created quickly and easily. A general knowledge of SilverStripe's
+[Datamodel](/topics/datamodel) is useful before creating a custom report. 
 
-Inside the Mysite/Code folder - your projects code, create a file called `CustomSideReport` or `MyProjectSiteReport` and
-inside this file we can add our site reports.
+Inside the *mysite/code* folder create a file called *CustomSideReport.php*. Inside this file we can add our site reports. 
 
-CustomSideReport.php 
+The following example will list every Page on the current site.
+
+###CustomSideReport.php 
 
 	:::php
-	<?php
-	class CustomSideReport_NameOfReport extends SideReport {
+	class CustomSideReport_NameOfReport extends SS_Report {
+		
+		// the name of the report
 		public function title() {
-			// the name of our report
-		}
-		public function records() {
-			// what we want the report to return and what order
-		}
-		public function fieldsToShow() {
-			// which fields on that object do we want to show? Title, Author?
-		}
-	}
-	?>
-
-
-Now this won't do anything! You will just get a blank report that doesn't work! So for this to do something we have to
-fill in these 3 methods title() records() and fieldsToShow() till we have something like this. For example if you want
-to list every Page on your site!
-
-CustomSideReport.php
-
-	:::php
-	<?php
-	/** 
-	 * This report lists all the pages in the CMS
-	 * of type Page. Sorted by title.
-	 */
-	class CustomSideReport_AllPages extends SideReport {
-		public function title() {
-			// this is the title of the report
-			return "All Pages";
+			return 'All Pages';
 		}
 		
-		public function records() {
-			// the data the report returns all the dataobjects of type Page and sorted by title. See datamodel for more info
-			return Page::get()->sort("Title");
+		// what we want the report to return and what order
+		public function sourceRecords($params = null) {
+			return Page::get()->sort('Title');
 		}
 		
-		public function fieldsToShow() {
-			// fields you want to display. This will display a list of titles which link to the page in the cms. Handy!
-			return array(
-				"Title" => array("NestedTitle", array("2")),
+		// which fields on that object we want to show
+		public function columns() {
+			$fields = array(
+				'Title' => 'Title'
 			);
-		}	
+			
+			return $fields;
+		}
 	}
-	?>
-
-
-Reload the CMS and test it out for your self! You should be able to select the report and view all the pages.
+	
+More useful reports can be created by changing the `DataList` returned in the `sourceRecords` function.
 
 ## Notes
 
-*  Your CustomSideReport_ReportName must extend SideReport!
-*  You can have more then 1 report in the 1 file. Actually its recommended!. You should create 1 CustomSideReport.php
-file and add class's as you need them inside that for each report.
+*  `CustomSideReport_ReportName` must extend `SS_Report`
+*  It is recommended to place all custom reports in the 1 file.
+** Create a *CustomSideReport.php* file and add classes as you need them inside that for each report
 
 ## TODO

-*  More examples.
+*  How to format and make advanced reports.
