+!!! note "First time only"
+
+    You only need to clone the repository on your work machine the first time you work on a development for CABLE. The subsequent times, you can work from the same copy of the repository.
+
+On [CABLE's GitHub main page][CABLE-repo], click the `code` green button, choose the SSH protocol and copy the URL you need:

-Make sure to choose the appropriate protocol (HTTPS or SSH) for connecting to the remote repository. Note, you need to setup an access token to use HTTPS and SSH keys to use SSH.
+!!! warning "Change the protocol after cloning"
+
+    It is possible to change the access protocol to GitHub in your cloned repository if you realise you have chosen the wrong protocol, ie.:
+
+    - you have cloned using the HTTPS protocol but have SSH keys setup with GitHub
+    - or you have cloned using the SSH protocol but you have a personal access token setup with GitHub
+
+    To do this, check our FAQs. 
 
 On your local machine in a terminal, clone the repository:
 
 ```bash
 git clone <URL provided>
 ```
