# Requirements

## Client-side Rendering is currently available. 

## Required SSR Tag:

This tag is extremely important as it allows Intelligems to track package versions to ensure compatibility with new features.

```
const intelligems = require("@intelligems/headless/gatsby");

exports.onRenderBody = ({ setHtmlAttributes, setBodyAttributes }) => {
  setBodyAttributes(intelligems.IntelligemsVersionAttribute);
};
```
