@ -66,7 +66,12 @@ Here is an example of how to set the heap size via a `jvm.options.d/` file:
<1> Set the minimum heap size to 2g.
<2> Set the maximum heap size to 2g.

Using `jvm.options.d` is the preferred method for configuring the heap size for
production deployments.
It is also possible to set the heap size via the `ES_JAVA_OPTS` environment
variable. This is generally discouraged for production deployments but is useful
