What is a 1st file?

A 1st file contains information about a computer program or application. Typically composed as a plain text document, a “readme” file contains a natural language description of the application. The file ending 1st is partly an effort to compel readers to read the contents before running the application: the full file name of a file with this extension is “readme.1st”. A readme file can be composed of information such as the application name and version number, release date and purpose. It also may contain useful information about the system requirements, known issues and patent or licensing data.
