Clarification Needed on Custom Configuration Documentation

[azhuchkov]

The published configuration format appears to be outdated and does not accurately reflect the current state of the project's codebase, whether in the latest release 1.7.2 or the master branch. This discrepancy may prove frustrating for newcomers who might not be aware of this issue.

Additionally, it would be beneficial to improve navigation by cross-linking the GitHub repository and the project website. Including a link to the 'About' section on GitHub and adding a global link from 3b1b.github.io to the GitHub page would enhance user experience.

Thanks for bringing this up — both points are absolutely valid.

1. You're right that the published configuration format is currently out of sync with the actual code in version 1.7.2 and the master branch. This can indeed be confusing for new users. A review and update of the documentation and config examples would definitely help here.

2. Cross-linking the GitHub repository and the project website is a great suggestion. Adding a link in the GitHub “About” section and including a visible link on 3b1b.github.io to the GitHub repo would improve discoverability.
