+## Text Formatting Tips
+
+The way you format text affects the output quality.
+
+### Punctuation
+
+Use proper punctuation for natural pauses:
+
+```
+Good: "Hello! How are you today? I'm doing great."
+Bad: "Hello how are you today Im doing great"
+```
+
+### Emphasis
+
+Use formatting to suggest emphasis:
+
+```
+- ALL CAPS for louder/emphasized: "That was AMAZING!"
+- Italics for subtle emphasis: "I *really* enjoyed that"
+- Bold for strong emphasis: "This is **very** important"
+```
+
+<Note>
+  The model interprets these hints but results may vary.
+</Note>
+
