 ## The Light and Versatile Graphics Library
 
-Graphical User interfaces are necessary for visualizing information and interacting with certain aspects of an application. The Light and Versatile Graphics Library, also known as [LVGL](https://lvgl.io/), is an open-sourced library used to create graphical user-interfaces for microcontrollers and high-end processors. The light weight embedded library provides all the necessary widgets and user interface elements that will allow you to easily create user interfaces for displays and touch screens.

 ## Instructions
 
 ### Building a Simple GUI 
 
-This tutorial will guide you through building a basic user interface using the LVGL Library which you can download using the Arduino Library Manager. The setup for this tutorial requires you to first to upload the finished sketch file to the Portenta board. You will then connect the board to a USB-hub in order to connect it to an external monitor. Once the hub is powered externally, a graphical user interface with a label will be displayed on the screen.

 ### 1. The Basic Setup
 
-Begin by plugging your Portenta board into the computer using a USB-C cable and open the Arduino IDE or the Arduino Pro IDE. If this is your first time running Arduino sketch files on the board, we suggest you check out how to [set up the Portenta H7 for Arduino](setting-up-portenta) before you proceed.

 ### 4. Connect an External Monitor
 
-Compile and upload the sketch to your Portenta H7. At this point your board becomes the host. Unplug the board from your computer and connect it to the USB-hub along with a monitor that is connected to the HDMI port. Power up your hub by connecting it to an external power source and the monitor will display a label saying `Counter`.

 ### 5. Creating a Simple Counter
 
-Let's create a counter that increases each second and update the label on the screen. To do so, we will create a label and an updating task that is going to updated the label periodically and change its value. This is possible using an LVGL concept called 'Task'.

 ## Conclusion
 
-This tutorial shows how to build a simple user interface with your Portenta. Starting with a static view in the monitor and then converting it into a simple dynamic application that features an updating variable on the screen. The tutorial also shows how to  use the "task" feature of LVGL to run instructions recurrently.

 ### Next Steps
 Now that you know how to build a simple UI for a screen, you can try to add more labels to the screen to show various information or try out different LVGL widgets.
 
 ## Troubleshooting
 
-### Counter Label Doesn't Update
+### Counter Label Does Not Update
 
 - Make sure that the label and task are declared on top of the sketch, outside the `setup()` and `loop()` like a normal variable.
 - Check if the task has the same structure in the first declaration and the function creation.
 - Look inside the `loop()` and see if `lv_task_handler()` is there.
 
 ### Sketch Upload Troubleshooting
 
-- If you have troubles uploading the sketch, try to first set the board in bootloader mode, by clicking the reset button twice, then you should see the built-in LED pulsating.
-- If you uploaded the sketch and you don't have any output in the display, make sure you have `portenta_init_video()` in the `setup()`.
