This Claude tutorial is specifically designed to clearly explain: how to sign up and log in, choose a model, upload files, and enable Claude Code locally. Follow the steps, and you’ll be able to use Claude smoothly in one go.
1. Claude Sign-Up and Login: Account setup is the most critical
After opening the Claude official website, first create an account. The common method is registering with an email and completing the verification code check. If the page indicates your region or network is unavailable, it’s usually because the service isn’t covered there or the network environment is unstable. Try switching to a stable network and retry.
After logging in successfully, prioritize checking your profile and security settings—enabling two-factor authentication is safer. When logging into Claude on different devices later, try to stick to the same browser and the same account system to reduce the chance of triggering risk controls.
2. Web Basics: Choose a model, write requirements, upload files
When using Claude on the chat page, first make your goal specific: background, inputs, output format, and constraints—Claude is more likely to deliver a usable result in one pass. For complex reasoning or coding tasks, you can ask Claude to “derive step by step and give the conclusion.”
Claude supports uploading documents for summaries, key-point extraction, or outline generation. The cleaner the file (clear headings, well-structured paragraphs), the better the results. If an answer gets cut off, ask Claude to “continue from where it stopped,” or ask Claude to output a table of contents first and then expand section by section.
