1. To make error correction easier, it would be helpful to include a link to the article on GitHub at the end of the page. This would allow users to quickly navigate to the visual editor and make edits for typos or small mistakes. Such a feature significantly simplifies and speeds up the correction process.

2. Additionally, a “Report a Bug” button should be provided. Clicking it would open a GitHub Issue pre-filled with details about the article. This makes it easier for users to report issues or share suggestions when they cannot directly fix a problem or need to discuss it first.

MDN provides a great example of these features in action: MDN Example.
