+## Change how long Netdata stores metrics
+
+Netdata can store long-term, historical metrics out of the box. A custom database uses RAM to store recent metrics,
+ensuring dashboards and API queries are extremely responsive, while "spilling" historical metrics to disk. This
+configuration keeps RAM usage low while allowing for long-term, on-disk metrics storage.
+
+You can tweak this custom _database engine_ to store a much larger dataset than your system's available RAM,
+particularly if you allow Netdata to use slightly more RAM and disk space than the default configuration.
+
+Read our guide on [changing how long Netdata stores metrics](/docs/store/change-metrics-storage.md) to learn more and
+use our the embedded database engine to figure out the exact settings you'll need to store historical metrics right in
+the Agent's database.

-## Change how long Netdata stores metrics
-
-By default, Netdata uses a custom database which uses both RAM and the disk to store metrics. Recent metrics are stored
-in the system's RAM to keep access fast, while historical metrics are "spilled" to disk to keep RAM usage low.
-
-This custom database, which we call the _database engine_, allows you to store a much larger dataset than your system's
-available RAM.
-
-If you're not sure whether you're using the database engine, or want to tweak the default settings to store even more
-historical metrics, check out our tutorial: [**Changing how long Netdata stores
