+### Line Breaks
+
+Use `br` for soft line breaks within a paragraph (text continues in the same paragraph but on a new line):
+
+```ruby
+Notare::Document.create("output.docx") do |doc|
+  doc.p do
+    doc.text "Line one"
+    doc.br
+    doc.text "Line two (same paragraph)"

+    doc.text "123 Main Street"
+    doc.br
+    doc.text "Anytown, ST 12345"
+  end
+end
+```
+
+### Page Breaks
+
+Use `page_break` to force content to start on a new page:
+
+```ruby
+Notare::Document.create("output.docx") do |doc|
+  doc.h1 "Chapter 1"
+  doc.p "Content of chapter 1..."
+
+  doc.page_break
+
+  doc.h1 "Chapter 2"
+  doc.p "This starts on a new page."
+end
+```
+
+### Hyperlinks
+
+Add clickable links with `link`:
+
+```ruby
+Notare::Document.create("output.docx") do |doc|
+  # Link with custom text
+  doc.p do
+    doc.text "Visit "
+    doc.link "https://example.com", "our website"
+    doc.text " for more info."
+  end
+
+  # Link showing the URL as text
+  doc.p do
+    doc.text "URL: "
+    doc.link "https://example.com"
+  end
+
+  # Link with formatted content
+  doc.p do
