CLI Administration
------------------

Update your env.php with new credentials:

`php bin/magento setup:config:set --db-host="host" --db-name="database_name" --db-user="user" --db-password="pass"`

Change the base url:

```php bin/magento setup:store-config:set --base-url="http://someurl" --base-url-secure="https://somesecureurl"```

Compile all auto-generated classes:
  This happens automatically on page load but you really should do this manually.

```php bin/magento setup:di:compile```
