I will need to document this, but it's an important question. - All attachments are named using the datestamp, so the first attachment today would be called 2016-01-19-0.pdf or whatever. - The entries are also named using the datestamp, so we end up with a text file like 2016-01-19.md. - The markdown itself contains an explicit link to the attachment; it is automatically inserted during export. - However, datestamp acts as a primary key so that entries and attachments can be paired using another technique. Finally, attachments are linked to days. It is not currently supported to associate an attachment with a specific entry on any given day.
