README(Redirected from Readme)

A README file contains information about other files in a directory or archive of computer software. A form of documentation, it is usually a simple plain text file called READ.ME, README.TXT, README.md (for a text file using markdown markup), README.1ST – or simply README.
The file's name is generally always written in upper case. On Unix-like systems in particular this makes it easily noticed – both because lower case filenames are more usual, and because traditionally the ls command sorts and displays files in ASCIIbetical ordering, so that upper-case filenames appear first.
The contents typically include one or more of the following:
- Configuration instructions
- Installation instructions
- Operating instructions
- A file manifest (list of files included)
- Copyright and licensing information
- Contact information for the distributor or programmer
- Known bugs
- Credits and acknowledgments
- A changelog (usually for programmers)
- A news section (usually for users)

A README file is a requirement in the GNU Coding Standards Since the advent of the web as a de facto standard platform for software distribution, many software packages have moved (or occasionally, copied) some of the above ancillary files and pieces of information to a website or wiki, sometimes including the README itself, or sometimes leaving behind only a brief README file without all of the information required by a new user of the software. However, the popularity of GitHub (as well as older community conventions) has contributed towards README files still being widely used in open-source software (see next section).
As a generic termEdit
The expression "readme file" is also sometimes used generically, for files with a similar purpose. For example, the source code distributions of many free software packages, especially those following the Gnits Standards or those produced with GNU Autotools, include a standard set of readme files:
README General information AUTHORS Credits THANKS Acknowledgments CHANGELOG A detailed changelog, intended for programmers NEWS A basic changelog, intended for users INSTALL Installation instructions COPYING / LICENSE Copyright and licensing information BUGS Known bugs and instructions on reporting new ones
