- Tap on Select and select the file(s) you'd like to share to Showbie
- At the bottom toolbar, tap on Share
- Tap on Showbie here if you want to share your file as a .pages file or tap on Export at the bottom of the new menu that pops up (to share as other file formats)
- Select the file format that you'd like to export your work as
- Tap on either Showbie or Copy to Showbie - the latter is better for larger files
