In this post, we’ll talk about why documentation isn’t just a “nice to have” but a critical part of writing maintainable, collaborative, and scalable code. Whether you’re working solo or with a team, writing clear documentation can save time, prevent confusion, and make you look like a total pro to future-you and your teammates. We’ll cover the basics of good documentation, walk through some commonly used tools, and share tips and best practices to help you level up your doc game. Because let’s face it - your code might be clean, but if no one understands it (including you), it’s not doing its job.
