+## Using Serial Monitor with TinyUSB
 
+TinyUSB creates a USB CDC serial port called `SerialTinyUSB`. To use the Arduino Serial Monitor:
+
+**Option 1: Use SerialTinyUSB directly**
+```cpp
+SerialTinyUSB.begin(115200);
+SerialTinyUSB.println("Hello!");
+```
+
+**Option 2: Alias Serial (recommended for code portability)**
+```cpp
+#define Serial SerialTinyUSB
+
+void setup() {
+  Serial.begin(115200);
+  Serial.println("Hello!");
+}
+```
+
+Add the `#define` at the top of your sketch before any other includes.
