In order to email your notebook, the notebook must be converted to a plain text format, sent as an attachment to the recipient, and then the recipient must convert it back to the 'binary' notebook format.

Email attachments are normally converted to a well-defined MIME (Multi-purpose Internet Mail Extension) format. There is a program available that converts the notebook format, nb2mail, which converts the notebook to a notebook MIME format. The program is available at https://github.com/nfultz/nb2mail.

Usage is as follows:

• Install nb2mail using pip command (see website)
• Convert your selected notebook to MIME format
• Send to recipient
• The recipient MIME conversion process will store the file in the correct fashion (assuming they have also installed nb2mail)
