 - *Enable ssh access*: There is a script in the GitHub repository to enable ssh access `sshd_enable.sh`. You want to run it as the *root* user, otherwise you will not have the necessary permissions. Again, copy and paste the following in your SSM window:
 
 ```

 Once the script is completed, you should be able to ssh into your new instance. You can **Terminate** the SSM window. Then from your machine's terminal window, connect to the instance's *private* IPv4 address (given on the AWS instance summary page) with user name **jpluser**. For example, if the key file is `~/.ssh/aws_ec2_jupyter.pem` and the private IPv4 address is 100.104.70.37, then:
 
 ```
-$ ssh -i "~/.ssh/aws_ec2_jupyter.pem" [email protected] -L 9889:localhost:9889
+ssh -i "~/.ssh/aws_ec2_jupyter.pem" [email protected] -L 9889:localhost:9889
 ```
 
 The `-L` option indicates a tunnel from the local machine's port 9889 to the instance's port 9889; this will be used later to open Jupyterlab through your local machine's web browser.
