+
+Select is a collection of API methods, event handlers, event emitters and
+buttons (for the `Buttons` extension) for DataTables. It provides the following
+features, with an overview of how they are implemented:
+
+## Selection of rows, columns and cells. Whether an item is selected or not is
+   stored in:
+
+* rows: a `_select_selected` property which contains a boolean value of the
+  DataTables' `aoData` object for each row
+* columns: a `_select_selected` property which contains a boolean value of the
+  DataTables' `aoColumns` object for each column
+* cells: a `_selected_cells` property which contains an array of boolean values
+  of the `aoData` object for each row. The array is the same length as the
+  columns array, with each element of it representing a cell.
+
+This method of using boolean flags allows Select to operate when nodes have not
+been created for rows / cells (DataTables' defer rendering feature).
+
+## API methods
+
+A range of API methods are available for triggering selection and de-selection
+of rows. Methods are also available to configure the selection events that can
+be triggered by an end user (such as which items are to be selected). To a large
+extent, these of API methods *is* Select. It is basically a collection of helper
+functions that can be used to select items in a DataTable.
+
+Configuration of select is held in the object `_select` which is attached to the
+DataTables settings object on initialisation. Select being available on a table
+is not optional when Select is loaded, but its default is for selection only to
+be available via the API - so the end user wouldn't be able to select rows
+without additional configuration.
+
+The `_select` object contains the following properties:
+
+```
+{
+	items:string       - Can be `rows`, `columns` or `cells`. Defines what item 
+	                     will be selected if the user is allowed to activate row
+	                     selection using the mouse.
+	style:string       - Can be `none`, `single`, `multi` or `os`. Defines the
+	                     interaction style when selecting items
+	blurable:boolean   - If row selection can be cleared by clicking outside of
+	                     the table
+	toggleable:boolean - If row selection can be cancelled by repeated clicking
+	                     on the row
+	info:boolean       - If the selection summary should be shown in the table
+	                     information elements
+}
+```
+
+In addition to the API methods, Select also extends the DataTables selector
+options for rows, columns and cells adding a `selected` option to the selector
+options object, allowing the developer to select only selected items or
+unselected items.
+
+## Mouse selection of items
+
+Clicking on items can be used to select items. This is done by a simple event
+handler that will select the items using the API methods.
