What is a YML file?

The YML file format is used for scripts and source code files that follow human-readable data serialization standards, which were developed for a data-centric markup called YAML. The .yml file extension is used for these files, which are also known as YAML documents. YAML stands for YAML Ain't Markup Language.Formerly known as Yet Another Markup Language, YAML is based on languages like C, Python, Perl and XML. These .yml files are also based on the RFC 2822 electronic mail format. To indicate that YAML is more of a data-centric markup instead of a document markup, Yet Another Markup Language was changed to YAML Ain't Markup Language.These YML files can be opened by using Notepad and other standard text editing applications. These text editing tools can also be used to create and edit the code stored in a .yml file.
