# CDN

Welcome to the [Gcore CDN](https://gcore.com/cdn) documentation page! Here we explain how to use, configure, and troubleshoot Gcore's CDN.

CDN is a distributed content delivery network that allows your website to load faster in users' browsers, regardless of how far they are from the source server.

From the left-side menu, you can access in-depth documentation about CDN:

* **Getting started** – create and integrate a CDN resource with your website, configure the source site to avoid conflicts with the CDN
* **Billing** – how service costs are determined, how to pay for additional features
* **CDN resource options** – configuration of various CDN resource options, such as caching, security, HTTP headers, CORS, optimization for delivering large files and images
* **Origin group** – add and configure a group of origin websites from which the CDN resource will retrieve content
* **SSL certificates** – add your SSL certificate, issue a free Let's Encrypt certificate
* **Purge** – clear the CDN resource cache by specifying the URL, a regular expression, or the CDN resource whose entire cache will be cleared
* **Prefetch** – preload content onto CDN servers
* **Logs** – view and download free logs, enable the paid Row Logs option for more detailed information
* **Reports** – statistics, including traffic volume, response codes, cacheable traffic percentage
* **Grafana, Terraform** – Grafana plugin for CDN statistics, create and configure CDN resources using the Terraform plugin
* **Troubleshooting** – typical issues may arise when using CDN and how to fix them yourself
