You use Footnote component to inject some notes which are expanded upon later, i.e. footnotes:

Footnotes are marked in the text using the Footnote component. Then, they are displayed together where the next Footnotes component appears. This also means that you can have multiple footnote sections. In that case, the indexing of the notes will keep increasing, but each footnote will only appear as part of the next Footnotes section after it.

linkShared References

Multiple parts of the text can reference the same footnote. For that, the footnote must be given an id, and subsequent references to this footnote can only reference the id without providing additional content:

1linkSo this[Only one note](:Footnote (id=X)) and this[](:Footnote (id=X)) will reference the same thing.

2link

3link> :Footnotes

So thisOnly one note and this will reference the same thing.

linkRich Text Content

If you want to have rich content as part of a footnote, you can use the quoted version of the Footnote component to outline your content, and then refer to it using an id:

1linkSo this[](:Footnote (id=Y)) will reference a note with more involved text.

2link

3link> :Footnote id=Y

4link>

5link> So in this note we can have stuff:

6link> - Such as lists

7link> - Or **styled** text

8link> - Or any other markdown basically

9link

10link> :Footnotes

So this will reference a note with more involved text.
