Question: I would like to show 'Low Stock Notification' on my website.
I have set 'Only X left Threshold' globally.
Is there any possibility to set this for each product individually?

Answer: 
There is another way. **We should know that we can override the html template via RequireJS. We don't need to create a custom theme**. In your custom module, create a `requirejs-config.js`:

*app/code/{Vendor}/{Module\_Name}/view/frontend/requirejs-config.js*

```
var config = {
    map: {
        '*': {
            'Magento_Checkout/template/minicart/content.html':
                'Vendor_ModuleName/template/minicart/content.html'
        }
    }
};

```

A more explain we can read more [here](https://magento.stackexchange.com/questions/108788/how-to-override-template-files-for-magento2-extension/121702#121702).
Open file for modifying minicart contents: 

```
/app/design/frontend/your_theme/Theme/Magento_Checkout/web/template/minicart/content.html

```

Open file for modifying minicart product contents :

```
/app/design/frontend/Eglo/Theme/Magento_Checkout/web/template/minicart/item/default.html

```

After modification, You have to deploy the theme using `bin/magento setup:static-content:deploy`then it will show.

If modification is not populated then modify tempaltes in below directory for showing runtime changes:

```
/pub/static/frontend/Your_theme/Theme/en_US/Magento_Checkout/template/minicart

```
