Most developers write code every day. Fewer write about it well.
That's not a dig; technical writing is a genuinely different skill from coding. Most developers never formally learned it. We picked up habits along the way, some good, most not. The result is READMEs nobody reads, documentation nobody trusts, and blog posts that explain everything except the part the reader actually needed.
This covers what makes technical writing work — not in a vague "write clearly" way, but the specific patterns that make developer docs, tutorials, and articles genuinely useful to the people reading them.
Why Most Developer Documentation Fails
Bad documentation comes from one of two problems: the writer knows too much, or the reader gets too little context.
The curse of knowledge is real. When you've built something, every step feels obvious. You skip the parts that seem self-evident — and those are usually exactly where readers get stuck. The gap between what you think you explained and what someone unfamiliar with the system actually needs is almost always wider than it looks from the inside.
The second problem is structure. Most developers, when asked to write something up, start at the beginning and go to the end. But readers don't work that way. They scan. They jump to the section that looks relevant. They copy the code block before reading the paragraph above it. Writing that assumes a linear reader loses everyone else — which is the majority of people.
Good technical writing for developers starts from the reader's mental model, not the author's. What does this person already know? What will confuse them first? Where will they get stuck?
The Writing Patterns That Actually Work
Lead With What, Not How
Start with what the thing does before explaining how it does it. This sounds obvious. Most documentation still doesn't do it.
"This function takes a user ID and returns the account balance as a float" is a far more useful first sentence than three paragraphs on internal implementation. Get to the point fast. Cover the implementation after the reader knows what they're working with.
Write Shorter Sentences Than You Think You Need
Technical readers scan before they commit to reading. Long, nested sentences slow that scan down. They also introduce ambiguity — the more clauses in a sentence, the more ways it can be misread.
A rule worth keeping: if a sentence has more than two commas, split it. You'll almost always end up with two clearer sentences and no lost meaning.
Use Real Examples, Not Placeholder Ones
foo, bar, and baz have a long history in programming examples. They're also nearly useless for helping someone understand what something actually does.
When you write an example, use something that resembles a real use case. A function that processes orders, not one that processes items. A user model with actual field names. Real examples make patterns stick. Placeholder examples make readers do extra mental work just to translate your example into their situation.
State the Expected Output
Every code example should have a matching output. Not just the code block — what actually happens when it runs. The return value. The console log. The state change. Readers should be able to check their version against yours before moving forward.
This single habit removes more confusion from technical content than almost anything else.
How to Write a README That People Actually Use
A README has one job: help someone understand what the thing is, whether they need it, and how to get started.
In that order. Every README should answer those three questions before anything else — often in the first screen of text, before anyone scrolls.
A structure that consistently works:
One-line description. What does it do? Not what it is - what it does. "Sends automated Slack alerts when database queries exceed a time threshold" beats "A performance monitoring utility" every time.
Installation. The exact commands, in the exact order, starting from a clean system. Don't assume your environment. Specify Node version, Python version, system dependencies — whatever someone would actually need.
Quick start. The shortest path from zero to something working. Save the full API reference for later. Give the reader a small win first.
Configuration. What can be changed? What are the defaults? What breaks if you set something wrong?
Troubleshooting. The three most common errors. What they mean. How to fix them. This section saves enormous support time and makes users feel less alone when things go sideways.
In my experience, README quality correlates directly with project adoption in open source. Repositories with well-structured READMEs get more stars, more contributions, and more real usage, even when a competing project with worse documentation exists and does the same thing.
Writing Technical Blog Posts That Get Read
Dev.to readers are technically literate but busy. They skim the intro, scroll, and decide in about 15 seconds whether to keep reading. Technical writing for developers in a blog context means earning that decision fast.
A few things that make posts hold attention:
Start with the problem, not the solution:
"I needed to run 50 API calls concurrently without hitting rate limits" is a stronger opener than "Today I'll show you how to use Promise.allSettled." The first makes readers feel recognized. The second makes them wonder if they care.
Show real code from a real project:
Not pseudocode. Not simplified stubs. Actual code from something you built, with context for why you made those choices.
Show what you got wrong first:
Technical posts that share the failed approaches before the working one consistently outperform those that skip straight to the answer. Readers want to know they weren't the only one who tried the obvious thing that didn't work.
Cover one idea deeply:
A post covering 12 things teaches readers nothing they'll remember. One concept, explored with real depth, is more useful and more shareable than a survey of everything loosely related.
Resources like bloket.blog cover knowledge-sharing, learning community building, and content strategy in ways that are directly useful if you're thinking about making technical writing a consistent habit alongside your development work.
Mistakes That Make Developer Writing Hard to Follow
Assuming too much context:
State prerequisites explicitly. If your post requires Docker knowledge, say so in the first paragraph, not buried in step four when things inevitably break.
Using jargon before defining it:
Every technical field has terms that feel obvious to insiders. Define them the first time, even briefly. Readers who already know will skip it. Readers who don't will stay.
Burying the key point:
The thing the reader needs most often lands in paragraph five of ten. Put it where it will actually be found — usually earlier than instinct suggests.
Over-explaining the easy parts, under-explaining the hard ones:
Most technical writers spend too many words on setup steps readers can figure out on their own, and too few on the judgment calls readers genuinely can't make without guidance.
Writing docs after the fact:
Documentation written from memory is always less accurate than documentation written during the process. Write the README while you build. Take notes as you configure. The knowledge is freshest in the moment, clean it up later.
Building the Habit Without Making It a Chore
The next time you solve a non-trivial problem, write it up. Not for an audience — just for your future self. What was the problem? What did you try? What worked and why? That note, cleaned up slightly, is usually your best blog post.
Bloket is one platform worth exploring if you want to build structured learning resources or share technical knowledge in interactive formats — particularly useful if your content goes beyond static articles into guided learning experiences.
The developers who write well — who document clearly, share what they know, and explain their decisions — consistently move faster within their teams and contribute more to the communities around them. Not because writing is some separate skill layered on top of engineering, but because clear writing and clear thinking are two sides of the same habit.
Write one thing. Make it genuinely useful. Then write another.
