-It may happen that you used your Nano ESP32 for other projects than Alvik, or you need to replace it. In order to make your Nano ESP32 work with Alvik, there are few steps needed:
+In order for Alvik to work properly three things have to be set correctly:
 
-1. Install the micropython bootloader on it following [this guide](https://docs.arduino.cc/micropython/basics/board-installation/).
+1. The Nano ESP32 needs the [MicroPython firmware](https://labs.arduino.cc/en/labs/micropython) on it.
+2. The [latest libraries](https://github.com/arduino/arduino-alvik-mpy/releases) have to be placed in the Nano ESP32.
+3. The [latest firmware](https://github.com/arduino-libraries/Arduino_AlvikCarrier/releases) has to be uploaded to the STM32 microcontroller.
 
-2. Download the Alvik micropyton libraries
+Alvik comes with a preinstalled version of libraries and firmware, but in case you want to upgrade it or if something happens and you mess things up, here is the guide to reinstall both libraries and firmware.
 
-   1. Alvik micropython libraries from the [Alvik repository](https://github.com/arduino/arduino-alvik-mpy/tree/main)
-   2. ucPack libraries from the [ucPack repository](https://github.com/arduino/ucPack-mpy/tree/main)
+### MicroPython Firmware on the Nano ESP32
 
-3. Unzip both of the downloaded libraries in a single "Alvik" folder, open the Arduino Lab for MicroPython, go to the "files" tab and set the path to the unzipped folder on the Arduino Lab for Micropython
+Download and install the [Arduino Lab for MicroPython](https://labs.arduino.cc/en/labs/micropython), if you are able to connect the Arduino Nano ESP32 it means that you're board is ready. You have to see the **CONNECTED** yellow label at the bottom.

+If something goes wrong it means you need to upload the MicroPython firmware on the Nano ESP32.
 
+Follow [this guide](https://docs.arduino.cc/micropython/basics/board-installation/).
 
-4. Make sure your Alvik is OFF, connect it to your computer and then, turn it ON
+### How to Upload Libraries
 
-   ![Alvik USB Connection](assets/connecting-final.gif)
+You will find the latest instructions directly in the [repository](https://github.com/arduino/arduino-alvik-mpy/releases). Here are the main steps:
 
+1. Prepare file
 
+Download the repository and extract all the files in a specific folder that will become the main Alvik folder.
 
-5. Connect your Alvik to the Arduino Labs for micropython and open the "lib"
-   ![Setting the FW path on the Labs for micropython](assets/lib_folder.png)
+2. Remove old files
 
-6. Select the "Arduino-alvik" and move it to the "lib" folder in your Alvik.
-   ![Setting the FW path on the Labs for micropython](assets/moving_alvik_folder.png)
+Open **Arduino Lab for MicroPython** and **connect** Alvik. Then:
 
-7. Go back to the main folder and select the "ucPack-mpy-main" folder and move it next to the arduino_alvik inside the "lib" folder in your Nano ESP32.
-   ![Setting the FW path on the Labs for micropython](assets/moving_ucPack.png)
+- Click on the `files` icon
 
-8. Now go back to the main root of the files system on the Nano ESP32. Then in your local folder navigate to the examples folder once there, select the following files and move them to the main folder of the ESP32.
+- Click on a `files name` in the bottom left explorer windows.
 
-   1. demo.py
-   2. hand_follower.py
-   3. line_follower.py
-   4. main.py
-   5. touch_move.py
+- Click on the `bin` icon to delete it
 
-   ![Setting the FW path on the Labs for micropython](assets/moving_examples.png)
+- Repeat for all the files, from all folders
 
-With this last step, your Nano ESP32 has been set up with the Alvik out of the box experience and is ready to be used.
+![Delete all files](/Users/josegardel/Documents/arduino_GH/docs-content-private/content/hardware/08.edu/solution-and-kits/alvik/tutorials/user-manual/assets/delete_files.png)
 
-### Updating Alvik's Body (STM32)
+3. Install mpremote
 
-1. Download the [pre-compiled firmware](https://github.com/arduino-libraries/Arduino_AlvikCarrier/releases/latest) from the [Alvik Carrier GitHub reposiitory](https://github.com/arduino-libraries/Arduino_AlvikCarrier)
+[mpremote](https://docs.micropython.org/en/latest/reference/mpremote.html) is a Python module needed to upload files on the Nano ESP32. The minimum suggested mpremote release is 1.22.0. Be sure to have Python installed before proceeding!
 
-   This step will download a "firmware_x_x_x.bin" file, save it in your Alvik folder
+```
+(venv)$ pip install mpremote
+```
 
-2. Connect your Alvik to the Computer and to the Arduino Labs for Micropython. Then, go to the files tab and navigate to the folder where you stored the "firmware_x_x_x.bin"
-   ![Setting the FW path on the Labs for micropython](assets/firmware.png)

-   ![Setting the FW path on the Labs for micropython](assets/flashing_fw.png)
+```
+$ ./install.sh -p <device port>
+```
 
-After executing these commands, there will be updates of the process on the prompt, once the process finishes, the firmware of your alvik will be updated.
+Windows
+
+```
+> install.bat -p <device port>
+```
+
+The `install.*` script will copy all the needed files into your Alvik.
+
+The `<device port>` is the name of the USB port that your computer assigned to the Nano ESP32. There are several ways to find it, depending on your OS, for example:
+
+- You can use the Arduino IDE to discover the port, [follow this guide to know more.](https://support.arduino.cc/hc/en-us/articles/4406856349970-Select-board-and-port-in-Arduino-IDE)
+- You can check it by using the Arduino Lab for MicroPython by clicking `Connect` after connecting Alvik with the USB cable.
+- You can check the list of the USB devices attached to your PC.
+
+### How to Upload Firmware

-### Update Alvik's brain
-    - Update ESP32 Micropython Firmware
-    - Update Alvik's Library
 ### Hello Alvik! Your first program!
 
+Alvik is intended to be programmed with MicroPyton. We recommend you to install the [Arduino Lab for MicroPython](https://labs.arduino.cc/en/labs/micropython) editor.
+
+Now that all the previous steps have been set, let's see how to create custom programs for Alvik to move forward until detecting an object in front of it, Alvik will detect it, dodge it and continue on its way.
+
+
+**1. **Create an Alvik folder in your computer and set it as the path of the Arduino Lab for MicroPython IDE
+
+![Adding Alvik folder path to the IDE](/Users/josegardel/Documents/arduino_GH/docs-content-private/content/hardware/08.edu/solution-and-kits/alvik/tutorials/getting-started/assets/alvik_folder_path.png)
+
+**2. **Create a new file "obstacle_avoider.py" in your local folder
+
+![Creating obstacle_avoider.py file](/Users/josegardel/Documents/arduino_GH/docs-content-private/content/hardware/08.edu/solution-and-kits/alvik/tutorials/getting-started/assets/creating_file.png)
+
+**3. **Double click on the file to open it. Once it is opened, erase the text on it and add the following code.
+
+![Adding custom code](/Users/josegardel/Documents/arduino_GH/docs-content-private/content/hardware/08.edu/solution-and-kits/alvik/tutorials/getting-started/assets/adding_custom_code.gif)
+
+``` python
+from arduino_alvik import ArduinoAlvik
+from time import sleep_ms
+import sys
+
+alvik = ArduinoAlvik()
+alvik.begin()
+sleep_ms(5000)  #waiting for the robot to setup
+#robot.set_illuminator(0)
+distance = 10
+speed = 40 #rpm
+
+def turning():
+    alvik.set_wheels_speed(0,0)
+    sleep_ms(250)
+    alvik.set_wheels_speed(-35,-35)
+    sleep_ms(1500)
+    alvik.set_wheels_speed(35,-35)
+    sleep_ms(1000)
+
+while (True):
+
+    distance_l, distance_cl, distance_c, distance_r, distance_cr  = alvik.get_distance()
+    sleep_ms(50)
+    print(distance_c)
+
+    if distance_c < distance:
+        turning()
+    elif distance_cl < distance:
+        turning()
+    elif distance_cr < distance:
+        turning()
+    elif distance_l < distance:
+        turning()
+    elif distance_r < distance:
+        turning()
+    else:
+        alvik.set_wheels_speed(speed, speed)
+
+```
+
+**4. **Connect Alvik to your PC using the cable included in the box, under the tray.
+
+![Connecting Alvik to the PC](/Users/josegardel/Documents/arduino_GH/docs-content-private/content/hardware/08.edu/solution-and-kits/alvik/tutorials/getting-started/assets/connecting_alvik.gif)
+
+***Make sure that Alvik is OFF before connecting it to your computer.***
+
+**5. **Once Alvik is connected to the PC, connect it to the Arduino Lab for MicroPython and open the _main.py_ file in the Alvik folder. Once the file is opened let's replace the `import demo` statement by `import obstacle_avoider`.
+
+![Connecting Alvik to the IDE](/Users/josegardel/Documents/arduino_GH/docs-content-private/content/hardware/08.edu/solution-and-kits/alvik/tutorials/getting-started/assets/connecting_alvik_ide.gif)
+
+*** If you want to go back to the out of the box experience where you could select between reg, green and blue programs, you only need to modify the _main.py_ again replacing the `import obstacle_avoider` statement by `import demo`***
+
+**6. **The last step is to move the _obstacle_avoider.py_ file from the local repository to Alvik's memory.
+
+![Moving file from local to Alvik's memory](assets/local2memory.gif)
+
+You are now all set, disconnect Alvik from the computer, put some obstacles around Alvik, turn it ON and see how Alvik detects them and turns to avoid them.
