+# PDF Annotations
+
+The Syncfusion [.NET Core PDF library](https://www.syncfusion.com/document-processing/pdf-framework/net-core/pdf-library) provides powerful tools to create, read, and edit PDF documents. This library also includes features to add, edit, and manage annotations in PDF files, enabling effective markup and collaboration.
+
+## Steps to add annotations to a PDF
+
+Follow these steps to add a popup annotation to a PDF file using the Syncfusion library:
+
+Step 1. **Create a new project**: Set up a new C# Console Application project.
+
+Step 2. **Install NuGet package**: Add the [Syncfusion.Pdf.Net.Core](https://www.nuget.org/packages/Syncfusion.Pdf.Net.Core/) package to your .NET Standard application from [NuGet.org](https://www.nuget.org/).
+
+Step 3. **Include necessary namespaces**: Add the following namespaces to your `Program.cs` file:
+
+   ```csharp
+   using Syncfusion.Drawing;
+   using Syncfusion.Pdf;
+   using Syncfusion.Pdf.Graphics;
+   using Syncfusion.Pdf.Interactive;
+   using Syncfusion.Pdf.Parsing;
+   ```
+
+Step 4. **Code to add annotations**: Use the following code snippet in `Program.cs` to insert annotations into a PDF file:
+
+   ```csharp
+   // Create a FileStream object to read the input PDF file
+   using (FileStream inputFileStream = new FileStream("input.pdf", FileMode.Open, FileAccess.Read))
+   {
+       // Load the PDF document from the input stream
+       using (PdfLoadedDocument loadedDocument = new PdfLoadedDocument(inputFileStream))
+       {
+           // Access the first page of the PDF document
+           PdfPageBase loadedPage = loadedDocument.Pages[0];
+
+           // Create a new popup annotation
+           PdfPopupAnnotation popupAnnotation = new PdfPopupAnnotation(new RectangleF(100, 100, 20, 20), "Comment");          
+           // Set the icon for the popup annotation
+           popupAnnotation.Icon = PdfPopupIcon.Comment;       
+           // Set the color for the popup annotation
+           popupAnnotation.Color = new PdfColor(Color.Yellow);     
+           // Add the annotation to the page
+           loadedPage.Annotations.Add(popupAnnotation);
+
+           // Save the updated document
+           using (FileStream outputFileStream = new FileStream("output.pdf", FileMode.Create, FileAccess.Write))
+           {
+               loadedDocument.Save(outputFileStream);
+           }
+       }
+   }
+   ```
