+==============================================================================
+Before you can utilize the EC2 API tools, you must export several environment
+variables to your $SHELL. The easiest way to do this is to add them to your
+dotfiles. If you’re running the `bash` shell (the default), you’ll want to add
+them to `~/.bash_profile`. If this is the case, run `nano ~/.bash_profile` at
+a terminal to edit said file. zsh users will want to edit `~/.zprofile`
+instead.
+
+    export JAVA_HOME="/System/Library/Frameworks/JavaVM.framework/Home/"
+    export EC2_HOME="#{prefix.to_s}/"
+
+However, you’re still not ready to use the tools. You need to download your
+X.509 certificate and private key from Amazon Web Services. These files are
+available at the following URL:
+
+http://aws-portal.amazon.com/gp/aws/developer/account/index.html?action=access-key
+
+You should download two `.pem` files, one starting with `pk-`, and one
+starting with `cert-`. You need to put both into a folder in your home
+directory, `~/.ec2`, and then add the following to your profile file:
+
+    export EC2_PRIVATE_KEY="$(/bin/ls $HOME/.ec2/pk-*.pem)"
+    export EC2_CERT="$(/bin/ls $HOME/.ec2/cert-*.pem)"
