-const paragraph = new Paragraph({
+doc.addSection({
+    children: [
+        new Paragraph({
             text: "Bullet points",
             bullet: {
-        level: 0, //How deep you want the bullet to be
-    },
+            level: 0 //How deep you want the bullet to be
+          }
+        }),
+        new Paragraph({
+            text: "Are awesome",
+            bullet: {
