+## Frame Gallery
+
+We've designed a gallery of frames and animations that are included in the library! You may load and display them on your UNO R4 WiFi with the following code snippet:
+
+```arduino
+#include "Arduino_LED_Matrix.h"   // Include the LED_Matrix library
+#include "frames.h"               // Include a header file containing some custom icons
+
+ArduinoLEDMatrix matrix;          // Create an instance of the ArduinoLEDMatrix class
+
+void setup() {
+  Serial.begin(115200);           // Initialize serial communication at a baud rate of 115200
+  matrix.begin();                 // Initialize the LED matrix
+
+}
+
+void loop() {
+  // Load and display the basic emoji frame on the LED matrix
+  matrix.loadFrame(LEDMATRIX_EMOJI_BASIC);
+}
+```
+
+By changing the parameter in `matrix.loadFrame()` in the loop, you can choose among the available frames we designed. 
+
+The available frames are:
+- `LEDMATRIX_BLUETOOTH`
+- `LEDMATRIX_BOOTLOADER_ON`
+- `LEDMATRIX_CHIP`
+- `LEDMATRIX_CLOUD_WIFI`
+- `LEDMATRIX_DANGER`
+- `LEDMATRIX_EMOJI_BASIC`
+- `LEDMATRIX_EMOJI_HAPPY`
+- `LEDMATRIX_EMOJI_SAD`
+- `LEDMATRIX_HEART_BIG`
+- `LEDMATRIX_HEART_SMALL`
+- `LEDMATRIX_LIKE`
+- `LEDMATRIX_MUSIC_NOTE`
+- `LEDMATRIX_RESISTOR`
+- `LEDMATRIX_UNO`
+
+Alternatively, play one of the animations on the LED matrix like this:
+
+```arduino
+#include "Arduino_LED_Matrix.h"   //Include the LED_Matrix library
+#include "animation.h"            //Include animation.h header file
+
+// Create an instance of the ArduinoLEDMatrix class
+ArduinoLEDMatrix matrix;  
+
+void setup() {
+  Serial.begin(115200);
+  // you can also load frames at runtime, without stopping the refresh
+  matrix.loadSequence(LEDMATRIX_ANIMATION_STARTUP);
+  matrix.begin();
+  matrix.play(true);
+}
+
+void loop() {
+}
+```
+In this case, you change the parameter of `matrix.loadSequence()` in the setup to one of the available ones to display. 
+
+The available animations are:
+- `LEDMATRIX_ANIMATION_STARTUP`
+- `LEDMATRIX_ANIMATION_TETRIS_INTRO`
+- `LEDMATRIX_ANIMATION_ATMEGA`
+- `LEDMATRIX_ANIMATION_LED_BLINK_HORIZONTAL`
+- `LEDMATRIX_ANIMATION_LED_BLINK_VERTICAL`
+- `LEDMATRIX_ANIMATION_ARROWS_COMPASS`
+- `LEDMATRIX_ANIMATION_AUDIO_WAVEFORM`
+- `LEDMATRIX_ANIMATION_BATTERY`
+- `LEDMATRIX_ANIMATION_BOUNCING_BALL`
+- `LEDMATRIX_ANIMATION_BUG`
+- `LEDMATRIX_ANIMATION_CHECK`
+- `LEDMATRIX_ANIMATION_CLOUD`
+- `LEDMATRIX_ANIMATION_DOWNLOAD`
+- `LEDMATRIX_ANIMATION_DVD`
+- `LEDMATRIX_ANIMATION_HEARTBEAT_LINE`
+- `LEDMATRIX_ANIMATION_HEARTBEAT`
+- `LEDMATRIX_ANIMATION_INFINITY_LOOP_LOADER`
+- `LEDMATRIX_ANIMATION_LOAD_CLOCK`
+- `LEDMATRIX_ANIMATION_LOAD`
+- `LEDMATRIX_ANIMATION_LOCK`
+- `LEDMATRIX_ANIMATION_NOTIFICATION`
+- `LEDMATRIX_ANIMATION_OPENSOURCE`
+- `LEDMATRIX_ANIMATION_SPINNING_COIN`
+- `LEDMATRIX_ANIMATION_TETRIS`
+- `LEDMATRIX_ANIMATION_WIFI_SEARCH`

 ## Animation Generation
 We have developed a tool that is used to generate frames and animations to be rendered on the LED Matrix in your browser. This tool is part of [Arduino labs](https://labs.arduino.cc), and is therefore considered experimental software.
