On any given week, I might be working on 2-3 different projects at a time. I’ll often have to dip into an old project, start a new project, or assist another developer in their current project. When you’re dealing with so many files with so many different authors, you realize the importance of a well documented and updated README file. Every project has its own requirements, installation processes, coding styles, content management system, etc. A well documented README file can save a developer hours of time.
