What’s a README file?

Print anything with Printful



A readme file is included with software and contains information about installation, usage, legal terms, and more. It often includes the software name, version, and developer. The file is usually in plain text format and may include a version history or FAQ section.

A readme file is a text file often included with software that contains general information or instructions about the software. The specific nature of this information varies greatly from file to file; a readme file may contain installation instructions, general information on using the software, terms of service and other legal information, or any other information relating to the software. Most readme files include at least the name and version of the software, the name of the company or person who developed the software, and the date it was published. There is no general formula for writing a readme, however, and ultimately the content depends on the whim of the developer.

The “readme” name is intended to draw the user’s attention to the file as it often includes information necessary for the software to function properly. In many cases, the file name of a Readme file will be in uppercase and will be called “README.txt” or something similar. Some program directories move uppercase filenames to the top of any file listing, so capitalization emphasizes the readme file and again encourages the software user to read the file before using the program. Some readme files are actually titled “read me first” or something similar to further encourage readers to consult the documentation before running the software.

A Readme file can contain many different types of information of varying importance. In addition to file names and versions, which are usually included, readme files also often include a version history or change log that lists changes made to the software over time. A readme may also include a list of known issues or bugs that affect your use of the software. Some include less essential information such as credits or personal messages from the development team. For particularly simple programs, the readme file can actually serve as a user manual that educates the user on general use of the software.

Elaborate readme files are very rare, as developers usually prefer to lay out the necessary information in a simple, clear and concise way. A readme file is usually presented in a plain text format with a standard font and no images, unless the developer deems something more elaborate is needed. This simplicity removes unnecessary distractions and keeps the reader focused on the information. Sometimes, a Readme file is presented in a “frequently asked questions” or FAQ format. In that format, the developer anticipates the most common questions people might have about the software and provides clear, simple answers instead of cramming all the technical information into one block of text that people might not be inclined to read.
