+### Include in an email as an attachment
+
+To include a rendered pdf file in an email you can do the following:
+
+```ruby
+attachments['attachment.pdf'] = WickedPdf.new.pdf_from_string(
+  render_to_string('link_to_view.pdf.erb', layout: 'pdf')
+)
+```
+
+This will render the pdf to a string an include it in the email. This is very slow so make sure you schedule your email delivery in a job.
