+=== Memory
+Kibana has a default maximum memory limit of 1.4 GB, and in most cases, we recommend leaving this unconfigured.  In some scenarios, such as large reporting jobs,
+it may make sense to tweak limits to meet more specific requirements.
+
+You can modify this limit by setting `--max-old-space-size` in the `NODE_OPTIONS` environment variable. For deb and rpm, packages this is passed in via `/etc/default/kibana` and can be appended to the bottom of the file.
