+If you want to update, just replace the old phar with a new one.

+All commands require an additional `--storage` argument when using the phar. That's the path where your keys and certificates will be stored.
+On Unix you could use something like `--storage /etc/acme`.
+
+If you're using the phar, you can add a file called `acme-client.yml` next to it with the two keys `storage` and `server`.
+These values will be used as default if you don't specify them, but you can still use another server by explicitly adding it as argument.
