 ## Cloning using SSH
 
-Using SSH to interact with the repository required you to copy an SSH key file to GitLab. If you have no such key, you will have to generate it.
+Using SSH to interact with the repository required you to copy an SSH key file to GitLab. If you have no such key, **and only if you do not already have one** (otherwise existing files could be replaced, which is not what you want), you will have to generate it.
 
 The command to generate a key looks like:
 ```
-ssh-keygen -t ed25519 -f ~/.ssh/ed25519_gitlab
+ssh-keygen -t ed25519
 ```
 And creates two files: a file with a secret key and a file with a public key. 
 
 To display the contents of the file with the public key, use:
 ```
-cat ~/.ssh/ed25519_gitlab.pub
+cat ~/.ssh/id_ed25519.pub
 ```
 
 An example of how to generate a key pair and view the public key is given in the following screencast:
