cookbooks. This package type was a bit complicated because Chef uses RSA
signed requests as authentication with the registry.

+To work with the Chef package registry, you have to use [`knife`](https://docs.chef.io/workstation/knife/).
+
+## Authentication
+
+The Chef package registry does not use an username:password authentication but signed requests with a private:public key pair.
+Visit the package owner settings page to create the necessary key pair.
+Only the public key is stored inside Gitea. if you loose access to the private key you must re-generate the key pair.
+[Configure `knife`](https://docs.chef.io/workstation/knife_setup/) to use the downloaded private key with your Gitea username as `client_name`.
+
+## Configure the package registry
+
+To [configure `knife`](https://docs.chef.io/workstation/knife_setup/) to use the Gitea package registry add the url to the `~/.chef/config.rb` file.
