 ## Getting a Presentation Object
 
-In the Open XML SDK, the <xref:DocumentFormat.OpenXml.Packaging.PresentationDocument> class represents a presentation document package. To work with a presentation document, first create an instance of the `PresentationDocument` class, and then work with that instance. To create the class instance from the document call one of the `Open` method overloads. The code in this topic uses the <xref:DocumentFormat.OpenXml.Packaging.PresentationDocument.Open> method, which takes a file path as the first parameter to specify the file to open, and a Boolean value as the second parameter to specify whether a document is editable. Set this second parameter to `false` to open the file for read-only access, or `true` if you want to open the file for read/write access. The code in this topic opens the file twice, once to count the number of slides and once to delete a specific slide. When you count the number of slides in a presentation, it is best to open the file for read-only access to protect the file against accidental writing. The following `using` statement opens the file for read-only access. In this code example, the `presentationFile` parameter is a string that represents the path for the file from which you want to open the document.
