# Installing nRF Connect SDK (NCS) v3.2.1

![](/files/7qWjHDUjLdKl9dFhhALH)

The Conexio devices currently only support [<mark style="color:red;">ZephyrRTOS</mark>](https://www.zephyrproject.org/). To access all the features and capabilities, Nordic Semiconductor has developed the [<mark style="color:red;">nRF Connect SDK</mark>](https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/introduction.html) (NCS) which enables you to develop applications for nRF91 Series devices that power Conexio cellular devices.

{% hint style="info" %}
To support all the latest power and cellular features of the nRF91xx series SiP, Conexio Stratus device sample applications will only support nRF Connect SDK v3.2.1 or newer.
{% endhint %}

To make nRF Connect SDK installation a breeze, follow the following steps.

1. Download and install [Visual Studio Code](https://code.visualstudio.com/).
2. Next Download and install Nordic's [nRF Connect for VS Code](https://www.nordicsemi.com/Products/Development-tools/nRF-Connect-for-VS-Code) plugin.
3. Once installed successfully, you should see the nRF Connect for VS Code icon on the left side bar  of the VS Code.
4. Click Manage SDKs to install the nRF Connect SDK.<br>

## 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.conexiotech.com/master/programming-and-debugging/installing-nrf-connect-sdk-ncs-v3.2.1.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.
