The most complete installation and usage tutorial of GitHub Copilot
1. Tips
GitHub Copilot is free to try for one month so far, but the premise of the trial is to bind a bank card, because the follow-up will be automatically deducted, so please pay attention to the end date of the trial, and set the alarm clock to close the subscription.
The subscription price is US$10 per month and US$100 per year. Personally, I think it is a bit expensive. You can subscribe if you need it, but please carefully consider whether to subscribe.
