I have tried everything to complete it and it is not working plz help.
I would like to help!
I don't know what 76% is. Are you on the exercise called 2. nano?
Are you on Step 2? Did you open the nano editor? Did you type
echo "Welcome, Jane Doe"? Have you saved the file? Have you exited nano?
Do you see that I need a bit more info than "tried everything"?
