 When huginn first starts up it will create one user named, `admin`, with the password, `password`, along with a number of example agents for that user. Each new user will start off with a set of example agents.
 
+**Warning**: The **Require Confirmed Email** option *must* be **off** when you first start up the stack because the default user has a fake email address and will not allow you to login. If desired, you can upgrade the stack and turn email verification back on after changing the admin's email address.

 The Huggin web interface is served in the `huginn_web` container on port `3000`. In order to get web traffic to the container you have to create a Rancher load balancer and route the traffic to the container on port `3000`.
