# Refresh frequency

Retrain allows you to train your knowledge base with the latest content on it.

For "URL" data sources, you can define a refresh frequency at which you want to retrain it. Frequency offered are:

* Daily
* Weekly
* Monthly

## Domain-level refresh

Enabling this will apply the refresh frequency to all its child pages. 

* Open the knowledge base
* Click "Domain(s)" button
* Select the frequency from the dropdown

Now, your domain will always be scanned again for new URL(s), and the content of all URL(s) will be scrapped again.

## URL-level refresh

Enabling this will apply the refresh frequency to only the selected URL.

* Open the Knowledge base
* Click on the "URL" data source you want to schedule a retrain&#x20;
* Select the frequency from the dropdown
