+# Page Numbers
+
+> This feature allows you to set page numbers on each page
+
+?> **Note:** This feature only works on Headers and Footers
+
+```ts
+doc.Header.createParagraph().addRun(new TextRun("Page Number: ").pageNumber()).addRun(new TextRun("to ").numberOfTotalPages());
+```
+
+## 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();
+```
+
+For example:
+
+```ts
+const currentPageRun = new TextRun("Current Page Number: ").pageNumber();
+paragraph.addRun(currentPageRun);
+```
+
+## Total number of pages
+
+```ts
+numberOfTotalPages();
+```
+
+For example:
+
+```ts
+const lastPage = new TextRun("Total Page Number: ").numberOfTotalPages();
+paragraph.addRun(lastPage);
+```
+
+
+## Both
+
+You can combine the two to get "Page 2 of 10" effect:
+
+```ts
+const currentPageRun = new TextRun("Page ").pageNumber();
+const lastPage = new TextRun("of ").numberOfTotalPages();
+
+paragraph.addRun(currentPageRun);
+paragraph.addRun(lastPage);
+```
+
+Or:
+
+```ts
+doc.Header.createParagraph().addRun(new TextRun("Page ").pageNumber()).addRun(new TextRun("of ").numberOfTotalPages());
+```
+
