-## Example
-
-Here is another use-case where this tool can come in handy. If you use SSM Session Manager to SSH into your EC2 instances, you can use knox to switch between different AWS profiles and start an interactive session with a specific instance. Here is an example of how you can achieve this:
-
-```shell
-function ssh-aws () {
-    if [[ $# -ne 1 ]]; then
-        echo "Usage: ssh-aws <instance-id>"
-        return 1
-    fi
-    aws --profile pick ssm start-session --target $1 --document-name AWS-StartInteractiveCommand --parameters command="sudo su - \`id -un 9001\`"
-}
-```
-
-Now you can SSH into an EC2 instance using the following command:
-
-```
-$ ssh-aws i-00000000000000000
-```
