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: 
You can override this by adding this folder to your theme:

```
Magento_Checkout/web/template/minicart

```

In this folder you can create the content.html file. After a change made in this file make sure you flush your browser cache to see the changes.
Although Khoa TruongDinh's answer was really helpful, there are some details missing so here is a full example:

Working minicart example, copy the html template to:

```
[theme_path]/Magento_Theme/web/template/minicart/content.html

```

and in themes requirejs-config.js =>

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

```
