To add JavaScript to your website using HTML, you can follow these simple steps:

1. Create a new HTML file or open an existing one.

2. Add the `<script>` tag to your HTML file where you want the JavaScript code to be inserted. You can add the tag within the `<head>` or `<body>` sections of your HTML file, depending on where you want the script to be executed.

3. Within the `<script>` tag, add your JavaScript code. You can either write your code directly within the tag, or you can reference an external JavaScript file by providing the file path within the `src` attribute of the `<script>` tag.

Here's an example of what the HTML code would look like to add JavaScript directly within the `<script>` tag:

``` <!DOCTYPE html> <html> 

 <head>
   <title>My Website</title>
 </head>
 <body>

Hello World!

   <script>
     // Add your JavaScript code here
     alert("Hello World!");
   </script>
 </body>

</html> ```

And here's an example of how to add an external JavaScript file:

``` <!DOCTYPE html> <html> 

 <head>
   <title>My Website</title>
   <script src="myScript.js"></script>
 </head>
 <body>

Hello World!

 </body>

</html> ```

In the second example, the external JavaScript file "myScript.js" would contain the actual JavaScript code that you want to execute on your website.

Note that you should always make sure to place your `<script>` tag in the correct location in your HTML file, to ensure that your JavaScript code runs correctly. Additionally, you should always test your code to make sure that it is working as expected.
