 ## Current page number
 
-To get the current page number, call the `.pageNumber()` method on a `TextRun`. Then add the newly created `TextRun` into a paragraph
-
 ```ts
-pageNumber();
+PageNumber.CURRENT
 ```
 
 For example:
 
 ```ts
-const currentPageRun = new TextRun("Current Page Number: ").pageNumber();
-paragraph.addRun(currentPageRun);
+new Paragraph({
+    children: [
+        new TextRun({

-numberOfTotalPages();

-const lastPage = new TextRun("Total Page Number: ").numberOfTotalPages();
-paragraph.addRun(lastPage);
