# System Settings

## 🛠️ What are the system settings ?

The system settings allows you to configure your ngSurvey **on-premise** installation to meet your needs.

{% hint style="warning" %}
System settings are global and will affect all the ngSurvey users of your installation.
{% endhint %}

 You may configure following settings.

* [General settings](/installation-setup/system-settings/general.md) to setup default surveys or to disable the automatic login page redirection on your installation.
* [Mail server](/installation-setup/system-settings/mailing-server.md) that will be used to send out emails.
* [Bounce account](/installation-setup/system-settings/bounce-account.md) that will handle all invalid emails from [email invitations](/form-management/campaigns/campaign/email-distribution.md).
* Google related service like [Captcha](/installation-setup/system-settings/google/captcha.md) or [Google Service Accounts](/installation-setup/system-settings/google/service-account.md).
* [Accounts](/installation-setup/system-settings/mobile-messenging/twilio.md) to handle mobile SMS messages.
* [IPStack](/installation-setup/system-settings/third-party-apis/ipstack.md) to handle [IP geolocation](/form-management/form-designer/geolocation/ip-address-location.md).
* [Active Directory](/installation-setup/system-settings/active-directory-settings.md) to setup an Active Directory server for authentication.
* [Microsoft](/installation-setup/system-settings/third-party-apis/microsoft.md) related services like Cognitive or Text analytics services to handle your [automatic translations](/form-management/form-designer/multi-language-forms/auto-translation.md) and [sentiment analysis](/form-management/reports/text-reports/sentiment-analysis.md).
* [AI Provider](/ai-suite.md) to couple the power of AI to ngSurvey.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ngsurvey.com/installation-setup/system-settings.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
