# Customizing the Deployment Configurations

The Payment Hub EE's Helm chart picks sensible defaults for most configuration options, but it's certainly possible to customize all aspects by depending on the Helm chart and adding a custom `values.yml` file. This way we can fine-tune most aspects of the deployment, including but not limited to:

* number of Zeebe brokers in the Zeebe cluster
* number of partitions
* replication factor 
* CPU and IO resources allocated to the orchestration engine
* whether or not Zeebe's Elasticsearch and Kibana are enabled
* Operations app MySQL parameters
* Connectors' active Spring profile
* etc

For an actual example of configuration customization, see the sample Large environment's helm chart at <https://github.com/openMF/ph-ee-env-labs/tree/master/helm/payment-hub-large>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://mifos.gitbook.io/docs/payment-hub-ee/overview/installation-instructions/custom-installations/customizing-the-deployment-configurations.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
