Found a code snippet in a tutorial and have no idea what it does? Copilot Chat can translate it into plain English, line by line, so you can decide whether to actually run it. This guide walks you through the exact questions to ask, in the order that works best for a complete beginner.

💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.

✅ Before you start

A GitHub account (free to create at github.com — just an email and a password).
A Copilot plan. There's a free tier with a limited number of chats, paid plans for heavier use, and free seats for verified students and open-source maintainers. If you're unsure, sign in and look for the "Try Copilot" prompt — it will tell you which plan you're on.
A web browser (Chrome, Firefox, Edge, or Safari). If you prefer, you can do the same thing in VS Code with the Copilot extension installed, but this guide sticks to the web.
A code snippet to test with — keep a tutorial, blog, or Stack Overflow answer open in another tab.
About 5–10 minutes.

Step 1 of 6

Open Copilot Chat in your browser

Head to github.com and sign in. Once you're on the home page, look for a Copilot icon in the top navigation bar — it usually looks like a small spark or chat bubble. Click it, and a chat panel slides open from the side of the page. On a paid plan you get generous chat limits; on the free tier you may get a small number of chats per month.

💬 Example(no typing yet — just opening the chat)

🔄 If it looks different

If you don't see the icon, try the profile menu (your avatar) in the top-right and look for a "Copilot" or "Try Copilot" link.

✅ You'll know it worked when

a chat box appears at the bottom of the panel with a prompt like "Ask Copilot" or "Type a message."

Step 2 of 6

Paste the code snippet into the chat

Go back to the page where you found the code. Select the snippet with your mouse, copy it (Ctrl+C on Windows, Cmd+C on Mac), then click into the Copilot chat box and paste it (Ctrl+V / Cmd+V). The text appears as a code block — a grey box with monospaced font — so it's easy to read. If the snippet is very long, paste only the first 10–20 lines first; you can always add more later. Don't paste any secrets like API keys, passwords, or private tokens — replace those with placeholders such as "YOUR_API_KEY" first.

💬 Examplea real-looking snippet you might paste: `import requests; r = requests.get("https://api.example.com"); print(r.json())`

✅ You'll know it worked when

the code shows up formatted in the chat, with the assistant waiting below for your next message.

Step 3 of 6

Ask for a plain-English explanation

Now type a clear instruction in the chat box. The trick is to say exactly what you want and how you want it explained — a line-by-line breakdown is usually the most useful starting point. After you press Enter, Copilot writes back a multi-paragraph explanation right in the same chat. If instead you get more code, rephrase your prompt to start with the word "Explain..." rather than "What is this..."

💬 Try typing this"Explain this code line by line, like I'm 12 years old and have never programmed before."➤

✅ You'll know it worked when

Copilot describes what each line does in everyday words, not technical jargon — and ideally gives a one-sentence summary at the top.

Step 4 of 6

Drill into the parts you still don't get

Read Copilot's answer and pick the one sentence that's still confusing. Type a new question that points at exactly that part — the more specific you are, the better the answer. If the explanation still uses words you don't know, ask for an analogy. Each follow-up sits in the same chat, so you can scroll up to see the full conversation and Copilot remembers what you already asked.

💬 Try typing this"Can you explain `requests.get(...)` like I'm ordering food at a restaurant?"➤

✅ You'll know it worked when

you can summarize the snippet in your own words to a friend without looking back at the chat.

Drill into the parts you still don't get

Step 5 of 6

Ask about safety before you run it

Now the important question: should you actually use this code? Type a new prompt asking Copilot to flag risks. It can't actually run the code for you, but it can spot common things to check — hardcoded URLs, missing error handling, dependencies you might not have installed, or commands that delete files. Treat its answer as a starting checklist, not a guarantee; you still need to test in a safe place like an online playground or a throwaway folder.

💬 Try typing this"Are there any security risks, missing dependencies, or things that could break if I run this on my computer?"➤

✅ You'll know it worked when

Copilot names at least one concrete thing to check, like a library you'd need to install or a permission it requires.

Next step ↓

Step 6 of 6

Save the explanation for later

Hover over Copilot's answer and look for a small copy icon (two overlapping squares) at the top-right of the message. Click it to copy the whole reply, then paste it into a note app, a Google Doc, or an email to yourself. If there's no copy button, just select the text with your mouse and copy it the normal way. Saving now means you can come back to the explanation later without re-asking the same questions — and you have a record of what the snippet does in case you forget.

💬 Example(no typing — just clicking the copy icon and pasting into a note)

✅ You'll know it worked when

you can open your notes app and read the explanation back, with the original code snippet included.

⚠️ Common mistakes

Asking without context. If you just paste code and type "what is this?", Copilot guesses at your skill level and may give an answer full of jargon. The fix: tell it up front that you're a beginner — the example phrase in Step 3 works well.
Trusting the explanation as proof of safety. Copilot can confidently misread code, and it can't actually test it for you. The fix: always run unfamiliar snippets in a sandbox, a throwaway folder, or a free online playground like replit.com before using them on real files.
Pasting private information. API keys, passwords, customer names, or your company's internal code shouldn't go into any AI chat. The fix: replace sensitive values with placeholders like "YOUR_API_KEY" or "<redacted>" before you copy the snippet.

🚀 Try it now

Open github.com, find any beginner Python tutorial (the official Python wiki has a "Hello, World" example), copy the first line of code, and ask Copilot: "What does this do, in one sentence?" That's it — one snippet, one sentence, one answer. You've just made Copilot your tutor.
