+==== Edit UMDsiplay0x File  ====
+\\
+The UMDisplay0x file contains the code to write to the LCD. We do have to edit this file to tell it which of the two LCD lines to display from the my_data.txt file
+\\
+<file>
+# write line 1 and 2 to the LCD
+lcd_string(" " + line1,LCD_LINE_1)
+lcd_string(" " + line2,LCD_LINE_2)
+</file>
+\\
+<color red>Line1</color> refers to the line in the <color red>my_data.txt</color> file. So if this was UMD3, then you would want lines 5 and 6. so this would be:
+\\
+    lcd_string(" " + line5,LCD_LINE_1)
+    lcd_string(" " + line6,LCD_LINE_2)
+\\
+<color red>LCD_LINE_1</color> refers to the Line on the LCD (Line 1 is the top, line 2 is the bottom)
+\\
+\\
+Edit the UMDisplay0x.py file by using:
+\\
+    sudo nano /home/pi/Python/UMDisplay0x.py
