Asked by TechiePenguin42
I'm a Junior Sys Admin working in internal IT, and I'm diving into some Linux processes as part of my training. My supervisor has set me up with some basic tasks to help me get comfortable with the command line. I'm also looking to document the installation steps for things like MySQL and Apache. I want to improve my documentation skills because I haven't had to do this much before, and I believe it's a valuable skill for my future. So, what do you all think makes for "good" documentation?

For tasks like installing MySQL or Apache, I prefer having the documentation in the form of code instead of detailed manuals. Using tools like Ansible for automation and keeping everything in a git repository with proper playbooks is ideal. It eliminates manual errors and keeps files up-to-date easily. Traditional step-by-step instructions can be helpful, but shouldn't always be the first option.

GitGuru101: I totally agree with this! Having everything version-controlled means you can track changes easily. But don’t forget about the end-user docs, which still need to be straightforward for general users.

CrispCommunicator45: Exactly! It’s also vital to maintain a clear repository of your documentation while also offering traditional methods like screen recordings for non-technical users.

Good documentation should be complete, current, and well-versioned. It’s helpful to have a change log to track updates. Also, ensure the structure is logical so readers can easily navigate through it. If it’s well-organized, people can find what they need without sifting through a chaotic mess.

QuickFix831: Absolutely! And maintaining clarity is key. I find it frustrating when documentation is all over the place.

StructuredThinker76: Right! But don’t overdo it; you must assume readers have some understanding of their job. If you make it too basic, you risk frustrating advanced users.

Make sure your documentation explains what it’s for, how to use it, and any specific configurations needed. Including context and detailed steps makes it accessible even to those unfamiliar with the topic. Also, a quick evaluation by someone else who hasn’t done it before can help find gaps you didn’t notice.

Usersta01: Peer reviews are so valuable! They can highlight issues you might not see because you're too familiar with the material.

TeachMeTech88: Exactly! And a straightforward style means avoiding jargon that could confuse your reader. Always assume someone might not know your specialized terms.

To create good documentation, make sure to write down every step you take during the process. It should be detailed enough that someone could follow your steps even if they know nothing about the task. Including screenshots can help, but be careful to avoid cluttered visuals; use clear and focused edits. Think of it this way: if someone else needs to understand your document tomorrow, could they do it easily?

PracticalHelper88: Absolutely! And be sure to use suitable editing tools for your screenshots. A full-screen capture from a 4K monitor can confuse people. Stick to what’s necessary, or use multiple windows thoughtfully.

Debater92: But, is documenting every single step necessary? Sometimes it might just make sense to record your screen while talking through the process instead. That way, you can keep it lively and informative without overwhelming detail.
