Learn a field from the ground up
Follow what each idea builds on, read at your level, and ask when you're stuck. No account needed until you want to ask.
Step 1: Pick a field and a starting point
Try a neighbouring field rather than your own. Entries say what they build on, so you can trace an unfamiliar result back to ideas you know.
Or search and filter on Research by field.
Step 2: Read one entry top to bottom
Most entries start with a one-line summary and an explanation written for a first-year university student, often with a small picture of the idea. The full technical text follows under Go deeper.
Read the Student explanation; it's quick, and it tells you how the field itself frames the idea. Then Go deeper.

Step 3: Follow the path to understanding
On any problem page, Path to understanding lists the entries to read first, from the foundations up to the problem. The Understanding map shows what rests on what across the whole wiki.
Step 4: Get an AI assistant to help you
An AI assistant is a chat app you can ask questions in plain words. Use it as a tutor next to the page. Try: “I know [your field]. Explain this idea using analogies from it, and tell me where the analogy breaks.”
Both have free plans; sign up with an email address.
AI can be confidently wrong. Check what it says against the page's sources, and never post AI output on DARC as if you had checked it yourself.
Step 5: Create your free DARC account
When you want to ask something, you need an account. Go to Sign in and choose Continue with Google, Continue with GitHub or Email me a link, whichever you see. There's no password to remember.
You get a public handle (like @ada). Your handle, name and profile picture are public; your email address never is.
If you use GitHub, your DARC handle is usually your GitHub username, which makes you easy to recognise across both.
Step 6: Ask when you're stuck
On an entry, Ask a question and then Post question, or reply in its Discussion with Comment. Say what you read and where you got lost; people answer there.
DARC doesn't send notifications about replies yet, so check back on the page.
Step 7: Watch the field move
Each entry has a Progress timeline of reviewed milestones. Live changes shows every accepted change on the site, as it happens.
Step 8: Turn what you learned into a contribution
The best time to improve an explanation is right after you've struggled with it. See Improve the explanations.
