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: 
first we have to override web/template files to our magento theme file,
in my case content.html

```
Magento_Checkout/web/template/minicart/content.html

```

After changes in `content.html` file, we have to deploy static file using command `php bin/magento setup:static-content:deploy`

OR 

You have to delete content.html(i have to change content in this file) file from `pub/static/frontend/Magento/buytea/en_US/Magento_Checkout/template/minicart` and reload page again.

Changes are applied.
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'
        }
    }
};

```
