+# Hyperlinks
+
+There are two types of hyperlinks: internal (pointing to a bookmark inside the document) and external (pointing to an external url).
+
+## Internal
+
+To create an internal hyperlink you need first to create a bookmark (the paragraph that will be the destination of the hyperlink) with `doc.createBookmark(anchor, text)`.
+
+A bookmark is composed of an anchor (an identifier) and the text displayed. After creating a bookmark just add it to a paragraph with `paragraph.addBookmark(bookmark)`
+
+For example:
+
+```ts
+const paragraph = this.doc.createParagraph();
+const bookmark = this.doc.createBookmark('anchorForChapter1', 'This is chapter1');
+paragraph.addBookmark(bookmark);
+```
+
+Then you can create an hyperlink pointing to that bookmark with `doc.createInternalHyperLink(anchor,text)`:
+
+```ts
+const paragraph = this.doc.createParagraph();
+const link = this.doc.createInternalHyperLink('anchorForChapter1', 'This is a link to chapter1');
+paragraph.addHyperLink(link);
+```
+
+## External
+
+To create an external hyperlink you just need to specify the url and the text of the link, then add it to a paragraph with `doc.createHyperlink(url, text)`:
+
+```ts
+const paragraph = this.doc.createParagraph();
+const link = this.doc.createHyperlink('https://docx.js.org', 'This is an external link');
+paragraph.addHyperLink(link);
+```
+
+
+## Styling an hyperlink
+
+It is possible to set the style of the text of an hyperlink. This can be done applying run formatting on `TextRun` property of the hyperlink.
+
+Example:
+
+```ts
+const link = this.doc.createHyperlink('https://docx.js.org', 'This is an external link');
+link.TextRun.bold().italics()
+```
