## Remarks

* The `ern platform config <key> [value]` command is rarely used. &#x20;
* All current configuration values are already set and retrieved transparently through the use of commands that rely on the local platform configuration. &#x20;
* If a value is not provided, the `ern platform config <key> [value]` command reads the value associated with the specified key and logs it in the terminal. &#x20;
* If a value is provided, the `ern platform config <key> [value]` command sets the value associated with the given key with the specified value, overwriting any existing value stored for this key.
