+# AWS Role Trust Update
+
+A quick utility for updating AWS IAM role trust policies to allow other roles to assume this policy
+
+```console
+aws-role-trust-update -role-name <rolename here> -arn <awn arn here>
+```
+
+## Help
+
+Make sure that the aws cli tool has been installed and has been configured.  If not you can use the following environment variables:
+
+- AWS_ACCESS_KEY
+- AWS_SECRET_KEY
+
+### Existing Role ARN
+
+To get an existing roles ARN you can do the following with the AWS cli
+
+```console
+aws iam get-role --role-name <another role that is attached to an ec2 instance> | grep "Arn" | awk '{ print substr($2,2,length($2)-2) }'
+```
