### TLS/SSL Best Practices:

We will update our TLS/SSL configuration from time to time and consider best practices / recommendations on a case by case basis. We err on the side of ensuring that communicating with Acquire is always secure, and so our TLS/SSL configuration may result in older or manually configured clients not being able to talk to Acquire. We announce TLS/SSL configuration changes as a "Product Update" in the Acquire application and for additional information about our TLS/SSL configuration please see our security page.

## 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://developer.acquire.io/master/acquire/acquire-build-requirement/requirement-for-acquire.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.
