+### Downloading from multiple sites at once
+
+To do this, simply list the site names separated by commas:
+
+```sh
+npm run grab --- --sites=example1.com,example2.com
+```
+
+To avoid mixing guides from different sites into a single output file, we can also automatically split the output into separate files based on the site name:
+
+```sh
+npm run grab --- --sites=example1.com,example2.com --output=guides/{site}.xml
+```
+
 ### Parallel downloading
 
 By default, the guide for each channel is downloaded one by one, but you can change this behavior by increasing the number of simultaneous requests using the `--maxConnections` attribute:
 
 ```sh
-npm run grab --- --site=example.com --maxConnections=10
+npm run grab --- --sites=example.com --maxConnections=10
 ```
 
 But be aware that under heavy load some sites may start return an error or completely block your access.
