-# SCRIPT:        SETUP_TEMPLATE.sh
-# USAGE:         bash SETUP_TEMPLATE.sh | ./SETUP_TEMPLATE.sh
-# PURPOSE:       Shell script that prompts the user for their GitHub username, email name of their project and
-#                the type of project that it is. Then it will replace the author's (josee9988) username and email
-#                with the new ones (the user that is using this template). It will fully remove the LICENSE file,
-#                delete all of the content of the README.md file, and add a simple header,
-#                delete all of the content of the CHANGELOG.md and add a basic CHANGELOG versioning and 1st version,
-#                then this script will auto remove itself, to leave the new project without this file (SETUP_TEMPLATE.sh).
-# TITLE:         SETUP_TEMPLATE
-# AUTHOR:        Jose Gracia
-# VERSION:       See in CHANGELOG.md
-# NOTES:         This script will auto remove itself, and in case of wanting to run it again, the user must download
-#                it again or do a 'git stash' and revert the changes.
