-I created this installation for Vagrant/VirtualBox because I couldn't get email
-working from the Docker image.
+Setup Huginn under VirtualBox, with minimal configuration required.
+
+If you know the settings you will use for your Huginn installation (such
+as SMTP host, MySQL settings, etc) you can:
+
+- Clone this repository: `git clone https://github.com/m0nty/huginn-vagrant.git`
+- Jump straight in with `./setup.sh` and follow the prompts. No attempt 
+  is made to validate your input while you do this.
+
+If you prefer to edit the config files yourself:
 
 - Clone this repository: `git clone https://github.com/m0nty/huginn-vagrant.git`
-- Either use ./setup.sh for semi-automatic configuration via a dialog interface.
-  (If you do this, skip down to the line about config.vm.box below.) Or ...
 - Edit the `env` file, which will be copied to `/home/huginn/huginn/.env`
   (look for the FIXME comments in the file to see what you need to adjust).
 - Edit `provision.sh` and change the MySQL passwords for the root MySQL user and
   the Huginn DB user (search for FIXME again).
 - Edit the `Vagrantfile` if you want to change the virtual machine settings. I've
   gone with `vb.memory = "1024"` which you might want to increase if you think
-  your Huginn needs more.
-- You might want to change this line `config.vm.box = "ubuntu/trusty64"` if your
+  your Huginn is going to be busier.
+- You might want to change the line `config.vm.box = "ubuntu/trusty64"` if your
   PC can't run 64-bit images.
 - Edit the `huginn` file if you want to change the listening address and port for
   your Huginn instance.
