-Basic authentication using an API password is deprecated and will soon no longer work.
-Visit https://developer.github.com/changes/2020-02-14-deprecating-password-auth
-for more information around suggested workarounds and removal dates.
-"""
+Authentication will be made via access token.
+To generate your personal access token visit https://github.com/settings/tokens.
+
+NOTE:
+Never hardcode any credential information in the code. Always use an environment
+file to store the private information and use the `os` module to get the information
+during runtime.
 
+Create a ".env" file in the root directory and write these two lines in that file
+with your token::
+
+#!/usr/bin/env bash
+export USER_TOKEN=""
