You ignored a list of requirements including "My pull request has a descriptive title (not a vague title like Update index.md)". Descriptive titles and good explanations of changes are necessary for a well maintained codebase. Free Code Camp is choosing to relax some of its requirements to help people reach their Hacktoberfest goals, but this PR would normally be rejected. In the future, please help repository maintainers by providing useful titles and do not ignore contributing guidelines or requirements.
