Write Footnotes with MultiMarkdown

iA Writer 3 makes it easy to add inline footnotes to your text. You can write it out like this:

Here is normal text[^Write the footnote text in brackets] and the normal text continues. The footnote will be automatically generated in the preview.

…or you can click the button in the toolbar on OSX and configure the keyboard on iOS to support footnotes.

The above tip works on iOS, Mac and Android
