# Deploy HCM

High-level overview of DIGIT HCM deployment

## Basics

DIGIT is an open-source, customizable platform that lends itself to extensibility. New modules can be built on top of the platform to suit new use-cases, or existing modules can be modified or replaced. To enable this, in addition to deploying DIGIT, a CI/CD pipeline should be set up. CD/CI pipelines enable the end user to automate & simplify the build/deploy process.

DIGIT comes with configurable "CI as code", "Deploy as code", etc.. which can be utilized to set up the pipelines and deploy new modules. More on that in the steps below.

<mark style="color:orange;">**Note: Changing the DIGIT code has implications for upgrades. That is, you may not be able to upgrade to the latest version of DIGIT depending on the changes that have been made. New modules are generally not a problem for upgrades.**</mark>

## 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://docs.digit.org/health/v2.0/deploy/installation/production-setup/deploy-hcm.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.
