+### regenerate-thumbnails.js
+
+Regenerating local video thumbnails could be useful because new PeerTube releases may increase thumbnail sizes:
+
+```
+$ cd /var/www/peertube/peertube-latest
+$ sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run regenerate-thumbnails
+```
+
 ### create-transcoding-job.js
 
 You can use this script to force transcoding of an existing video. PeerTube needs to be running.
