If you wish to add information to a wiki that is similar to what is already posted,how or where should the information be added?

A) In a new wiki
B) As footnotes to the current file
C) In the same file but under a new heading
D) On a new wiki
E) By expanding the existing article or adding a subpage

The best choice is to expand the existing article or add a subpage, as this allows for continuity and coherence within the wiki. Adding information under a new heading within the same file can also work, but expanding the existing article or adding a subpage is generally preferred. Creating a new wiki or adding footnotes may not be necessary or relevant.
