+      Before you can use these tools you must export some variables to your $SHELL
+      and create a file containing your aws credentials.
+
+      You can access your AWS access ID and AWS secret key:
+      http://aws-portal.amazon.com/gp/aws/developer/account/index.html?action=access-key
+
+      You must create the file $HOME/.aws-credentials-master, here is a template:
+
+      # Enter the AWS Keys without the < or >
+      # You can either use the AWS Accounts access keys and they can be found at
+      # http://aws.amazon.com under Account->Security Credentials
+      # or you can use the access keys of a user created with IAM
+      AWSAccessKeyId=<Write your AWS access ID>
+      AWSSecretKey=<Write your AWS secret key>
+
+      To preserve your credentials don't forget to:
+      chmod 600 $HOME/.aws-credentials-master
+
+      To export the needed variables, add them to your dotfiles.
+        * On Bash, add them to `~/.bash_profile`.
+        * On Zsh, add them to `~/.zprofile` instead.
+      export JAVA_HOME="/Library/Java/Home/"
+      export AWS_IAM_HOME="#{prefix}/jars"
+      export AWS_CREDENTIAL_FILE=$HOME/.aws-credentials-master
+    EOS
