+
+The `partialCached` template function can offer significant performance gains for complex templates that don't need to be re-rendered on every invocation.
+
+**Note:** Each Site (or language) has its own `partialCached` cache, so each site will execute a partial once.
+
+Here is the simplest usage:
+
+```
+{{ partialCached "footer.html" . }}
+```
+
+You can also pass additional parameters to `partialCached` to create *variants* of the cached partial. For example, if you have a complex partial that should be identical when rendered for pages within the same section, you could use a variant based upon section so that the partial is only rendered once per section:
+
+{{< code file="partial-cached-example.html" >}}
+{{ partialCached "footer.html" . .Section }}
+{{< /code >}}
+
+If you need to pass additional parameters to create unique variants, you can pass as many variant parameters as you need:
+
+```
+{{ partialCached "footer.html" . .Params.country .Params.province }}
+```
+
+Note that the variant parameters are not made available to the underlying partial template. They are only use to create a unique cache key. Since Hugo `0.61.0` you can use any object as cache key(s), not just strings.
