+# Caching
+
+## Drivers
+
+You can change your cache driver by setting the environment variable in your configuration file. To change the default driver pass `CACHE_DRIVER` as an environment variable.
+
+### File (default)
+
+{% hint style="info" %}
+`v0.13.1` contains a change to `file` as the default driver to improve performance.
+{% endhint %}
+
+This is the default cache driver and fine in most use cases, especially if the container runs on the same host system.
+
+### Database
+
+Using the database cache driver can be used if you're running multiple instances and want to share the cache. 
+
+Change `CACHE_DRIVER` to `database` in your environment variables.
+
+### Redis
+
+Using Redis cache driver can also be used if you're running multiple instances or don't want to use the container's file system as the cache. 
+
+Change `CACHE_DRIVER` to `redis` in your environment variables.
