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
Start near the roots: the Mathematics and Algorithms fields. In an entry's sidebar, a short Builds on list means it's close to the foundations.
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 slowly and look up every word in Words on this page. It's fine to stop before Go deeper for now.
Use Words on this page for hard words and New to this? Read first for the best beginner reading.
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: “Explain this to me as if I'm in grade 10, with an example, then quiz me with three questions.”
Age rules differ: Claude needs you to be 18 or older. ChatGPT allows 13- to 17-year-olds with a parent's or guardian's permission, and some countries set a higher minimum age. Ask a parent, or skip this step: everything on DARC works without AI.
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.
DARC is for people aged 13 and over. If you're under 16, ask a parent or guardian before you sign up, and show them this page. If you use Google or GitHub, DARC shows the name and picture from that account, so pick one you're happy to show. DARC never asks for your age, school or anything else, and you don't need to share them.
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.
