How it works
What is a YML file?
YAML (YAML Ain't Markup Language), a human-readable data format used for data serialization, is used to format data in text files called YML files. It can be used to read and write data regardless of the computer language being used. YML files can be used in applications built in the majority of widely used programming languages, including C/C++, Ruby, Python, Java, Perl, C#, PHP, and others, because YAML syntax is language-independent.
