Ask the main part of your question in the title. This should be concise but informative.
Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.
Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.
Ask about the problem you're trying to solve. Don't focus too much on debugging your exact solution, as you may be going down the wrong path. Include as much information as you can about what you ultimately are trying to achieve. See more on this here: https://xyproblem.info/

Generally the best place to go for information on tools like VS Code is straight to the source. The official documentation may not be written for the absolute beginner but it's a solid jumping off point nonetheless.
