+### Volumes and data persistence
+Data can be persisted by [using volumes](https://docs.docker.com/storage/volumes/).
+Volumes allow to keep your data when renewing and/or updating container images:
+
+```shell
+# Create data volumes
+$ docker volume create shaarli-data
+$ docker volume create shaarli-cache
+
+# Create and start a Shaarli container using these volumes to persist data
+$ docker create \
+    --name shaarli \
+    -v shaarli-cache:/var/www/shaarli/cache \
+    -v shaarli-data:/var/www/shaarli/data \
+    -p 8000:80 \

+$ docker start shaarli
