There is a pattern of “?” buttons throughout the application which make use of the `data-help-page` attribute. Whenever these buttons are pressed, the user is redirected to the corresponding wiki page by prepending the wiki root URL to the `data-help-page` attribute.
Since the current wiki has a different structure than the original, for example to link to [https://github.com/TriliumNext/Docs/blob/main/Wiki/tree-concepts.md](https://github.com/TriliumNext/Docs/blob/main/Wiki/tree-concepts.md) the `data-help-page` attribute must be set to `tree-concepts.md`.
For links to headings, simply add the heading after the `.md`: `tree-concepts.md#prefix`
