Learn Claude Code, one small step at a time

You might be wondering whether anyone can tell that Claude had a hand in the text you just wrote. Anthropic has announced it will start marking that text – just not visibly, and not yet.

You explain the same things to Claude Code in every new chat: what you call your files, what nobody should touch, what matters to you. Some of that the AI can write down on its own. This lesson shows you whether it already has.

Single, simple requests to Claude Code are behind you. This lesson walks one task through the whole cycle: a plan before anything moves, the work itself, and checking the result with your own eyes.

Anthropic published its own investigation into three incidents where Claude models reached out of the test lab, connectors move to a new MCP spec, and Dario Amodei explains why he doesn't want open-weights models banned.

Starting Claude Code in a folder that already holds your files: /init reads what is there and writes a CLAUDE.md out of it, and you read the result and dictate the corrections.

Do you type the same thing at the start of every conversation with Claude Code? Or has a long session ever drifted away from something you asked for at the beginning? Here is which requests belong in a file and which can happily stay

Claude Opus 5 becomes the default Opus model, /code-review moves to the background, the subagent nesting limit goes back up, and a new connector lets you ask Claude how its own users are actually using AI, occupation by occupation.

Creating your first CLAUDE.md file: how to have Claude Code write it, what to tell it in the interview, how to check that it really gets read, and what to do when an instruction is ignored.

You open Claude Code's configuration and find a column of switches with not one sentence of explanation? Or maybe one of them has been flipped for months and nobody remembers why? We go through the ones that matter, in groups.

This week in Claude Code: manual skill invocation via /verify and /code-review, filesystem isolation controls, and Anthropic grants for rare genetic disease research.

A pass through Claude Code's settings on day one: model and effort, thinking, automatic conversation compaction, permission mode – plus the place on disk where all of it ends up.

Picking a model looks like a detail, right up until the week you start bouncing off your plan's limit. In this guide we'll try to help you match a model to the work you do, and show what jumping between them costs.

Installing Claude Code step by step: where to find the terminal, one install command, logging in through the browser, and a first instruction given inside your own folder.

Sooner or later you have to pick a plan, and you may be wondering whether Pro is enough or whether to go straight for Max. We'll try to help you make that call.

This week: Sonnet 5 becomes the default model, Claude Science opens up to research labs, and Claude Code picks up a handful of small but useful fixes.

Setting up an account on claude.ai step by step: logging in without a password, the code from your inbox, phone verification, and a first conversation. Including two points worth pausing at, because those choices can't be undone later.
