How to write a tutorial

A tutorial teaches a person to do something by guiding them through it. The test of a good tutorial is simple: can a reader complete the task following your steps, without having to guess?

What it is

A tutorial is a step-by-step guide that walks a beginner through completing a task or achieving a result. It anticipates where people get stuck and solves those problems in advance.

Why it matters

Clear tutorials build trust and save people frustration. A reader who can follow your steps is a reader who comes back — and one who does not blame you when they fail because the steps were unclear.

How to write it

State what the reader will achieve. Open by telling them exactly what they will have at the end. "By the end, you will have published your first post."

Tell them what they need. List any prerequisites: tools, accounts, knowledge, or materials. A reader who hits a wall at step 2 because they were missing something will stop.

Break it into clear, sequential steps. One action per step, in the right order. Each step should do one thing and be easy to check.

Number the steps and use headings. Numbers give a clear path; headings let a reader jump back. For a long tutorial, use a table of contents.

Explain the why behind tricky steps. If a step is confusing or easy to get wrong, say why it matters. "Use the copy button, not the cut button, so the original stays."

Add screenshots or illustrations where they help. A picture at the point of confusion is worth a paragraph. If you use them, keep them clear and same-size.

Add a troubleshooting section. List the common problems and their fixes. This is where tutorials become genuinely useful.

End with what they have accomplished. Reassure and confirm: "You have now published your first post." Point to the next step down the line.

Typical structure

1. What you will achieve.
2. What you need.
3. Step 1 — Step N (each with a clear action and a why where needed).
4. Troubleshooting.
5. What you have done / what's next.

Common mistakes

Skipping a step because it is "obvious" to you. Too many actions in one step. No prerequisites listed. Screenshots that are not at the right point. No troubleshooting. Assuming the reader already knows your jargon.

Practical tips

• Follow your own steps from scratch to catch the missing ones.
• Use the article-outline generator to shape the steps first.
• Put yourself in a beginner's shoes at each step.

Checklist
