# Validate that it is youtube URL using regex
# If passes the validation move on to downloading the caption in English if available.
# If not post the user that the caption was not available
# On sumbit allow user to have a text box with the summary populated
# Find out if the text box can contain the copy option so that the summary can be saved elsewhere as per needs
