 If you do not have access to the installation server scheduled task, you can still automate the update process.
 
-To do so, you need to create a scheduled task, which need to call a specific URL: https://your.server.net/FreshRSS/p/i/?c=feed&a=actualize (it could be different depending on your installation). Depending on your application authentication method, you need to adapt the scheduled task.

 #### No authentication
 
 This is the most straightforward since you have a public instance; there is nothing special to configure:
 
 ```cron
-0 * * * * curl 'https://your.server.net/FreshRSS/p/i/?c=feed&a=actualize'
+0 * * * * curl 'https://freshrss.example.net/i/?c=feed&a=actualize'

 The scheduled task syntax to use will be the following:
 
 ```cron

 ### HTTP authentication
 
 In that case, the syntax in the two previous section are unusable. It means that you need to provide your credentials to the scheduled task. **Note that this method is highly discouraged since it means that your credentials will be in plain sight!**
 
 ```cron
