+Some examples of sending and receiving emails with Node.js.
+
+This uses the following libraries:
+
+* [emailjs](https://github.com/eleith/emailjs) for sending email
+* [node-imap](https://github.com/mscdex/node-imap) for receiving email
+* [mailparser](https://github.com/andris9/mailparser) for parsing received emails
+
+## Running
+
+Copy `config.json.example` to `config.json` and enter your email account details.
+
+Run `coffee send.coffee` to send yourself an email with an attachment.
+
+Run `coffee read.coffee` to receive the sent email and write the attachment back to disk with a new name.
