 Just like with Vagrant, you simply need to run the SetupEnvironment.sh script before running your tests. Getting the
 package onto Travis CI can be done through a package manager directly, as with the composer example above, or through
 through a wrapper script that pulls it directly from git.

+## Adding Additional Emails
+
+This package works by storing a copy of a working Dovecot mail directory and then copying that directory into the test environment. Adding a new email in means sending it to the running instance of Dovecot and then updating the resources directory to make sure those changes stick between uses. This can be done a number of ways.
+
+The preferred way is to connect a mail client to the running instance of Dovecot, and then using that to transfer the email in. Most mail clients, such as Mail.app, allow drag and drop transfer of emails between accounts. This method is simpliest because it does not require setting up an SMTP server, as it simply reuses an existing "real" account to create the message and then transfers it in. This was the method used to creating the initial set of emails.
+
+Another option is to enable postfix directly on the Vagrant instance and to use that to recieve messages. This gets a little more complicated because it does require getting a mail server setup and integrated with Dovecot. 
+
+A final method is to email testuser@tedivm.com with the desired message, and then to open an issue here to request it's inclusion. There is obviously a bit of turnaround here, so please attempt to add it in on your own and feel free to issue a pull request to get it included here.
