Sorry if this is not the right stackexchange.
I have used Git with Github and that works well.
I now want to use Git with my own website which is on a live site. My host provided me with a private SSH key specifically for my domain. The key was generated via a Git add-on for cPanel.
How can I add this second key, and then how does Git know which key to use?
I'm totally noob to this but I've been Googling for hours about this.
