+Then add an API key with label *ACME* and copy the new key.
 
-Follow the installation instructions appropriate for your platform and then run the configuration.
-
-```linode configure
+```sh
+export LINODE_API_KEY="..."
 ```
 
-Make sure Linode CLI is working correctly before proceeding.

 Due to the reload time of any changes in the DNS records, we have to use the `dnssleep` option to wait at least 15 minutes for the changes to take effect.
 
+Ok, let's issue a cert now:
+
 ```sh
 acme.sh --issue --dns dns_linode --dnssleep 900 -d example.com -d www.example.com
 ```
 
+The `LINODE_API_KEY` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+
 # Use custom API
 
 If your API is not supported yet, you can write your own DNS API.
