+2. `Use an SD card with a minimum capacity of 4 GB, formatted as FAT32 with a 32 KB allocation unit size.`
+3. `Then insert this SD card into your ESP32-CAM board.`
+4. `Connect your 'OV2640' camera to your ESP32-CAM board.`
+
+
+## 📦 Setup 
+1. `Refer to the 'circuit_camera-programming.png' diagram`
+2. `Install the 'Arduino IDE' software and open 'esp32-cam_camera.ino' with 5 other file`
+3. `File>Preferences>Additional Boards Manager URLs:(Click the double window button)`
+>Paste this code  
+```bash
+https://dl.espressif.com/dl/package_esp32_index.json
+```
+4. `Click 'OK'`  
+5. `Tools>Board>Boards Manager...`  
+6. `Search 'esp32' by Espressif Systems, and install it` 
+> ⚠️ **Warning:** Make sure you have installed the correct USB driver (CH340, CH341, FT232R / FTDI Driver, CP2102) before connecting the ESP32CAM to your computer.
+7. `Plug the ESP32CAM into your computer`
+8. `Tools>Board>esp32>'AI Thinker ESP32-CAM'`
+9. `Tools>Port>'Select the esp's port'`
+
+
+
+10. `Tools>Manage Libraries...>Install the libraries used in the code`
+11. `Click the 'upload ➡️' button`  
+✅ **To make sure it has been uploaded successfully, you should see the message 'Done uploading'** 
+> ⚠️ **Advisory for Developers:** If you want to try this project in the future with new generation boards and you want to add new features like using 'DS1302 real time module', you must have 3 unused pins.
+
+## 🎉 Run  
+1. `Refer to the 'circuit_camera.png' diagram`  
+2. `Let the electricity pass through the switch`  
+3. `Press the reset button on the esp32cam`  
+4. `You are ready to use your mini camera`
