A README file, usually named README.TXT or similar, is a text file that provides important information to software users or developers before installation or initial usage. It often includes details on compatibility issues, installation instructions, known bugs, coding standards, and other pertinent details that might not have been covered in formal documentation or online Help files.
Key Information Contained in README Files
Installation Instructions
These are typically step-by-step guides to help users correctly install the software. It ensures that the user has all the necessary components and follows the correct procedure.
Compatibility Issues
Since software might have compatibility issues with various hardware or operating system configurations, a README file usually highlights these issues discovered post the release of formal documentation.
Known Bugs and Limitations
Known bugs, workarounds, and limitations of the current version of the software are often listed to prepare the user for any possible inconveniences.
Importance in Software Development
Early Communication
A README file can serve as the primary means of communicating urgent updates or last-minute information to users.
Enhanced User Experience
Proper use of README files ensures that users can troubleshoot problems on their own before seeking technical support.
Examples of README File Contents
- Project Overview: A brief description of what the software does.
- Version Information: The current version and a changelog if applicable.
- Installation Guides: Detailed steps to install the software.
- System Requirements: Minimum system requirements for proper functioning.
- Usage Instructions: Basic guidelines on how to use the software.
- Contributors and Credits: Information about the authors and contributors.
- License Information: Terms under which the software can be used or modified.
Historical Context
The practice of including README files started in the early days of computing and has continued to be a standard part of software development. Initially, it was used to provide quick instructions and updates before the era of dynamic online documentation.
Comparisons with Other Forms of Documentation
README vs. Online Help
While README files offer critical upfront details, online Help files are usually more comprehensive and interactive, providing in-depth assistance through searchable databases.
README vs. Printed Documentation
README files complement printed documentation by quickly addressing issues that arise after formal documentation has been finalized and printed.
