فایل website's front-end ؟

سلام.میخوام کامپوننت آمار ExtraWatch را نصب کنم.راهنمای نصب میگه که یه کد را باید به website's front-end کپی کنم.ممنون میشم راهنمایی کنید دقیقا منظورش کچاست:

1. Select the HTML code below and copy it to a clipboard



2. Open editor of your website's front-end

This step may be different for every CMS.
You need to find where's your website frontend saved as HTML and the modify that file.
Or ask your webmaster do to it for you!
3. Find the </body> tag
This is a footer of my website ©MyWebsite.com
</body>
</html>
4. Paste this code before the </body> tag
This is a footer of my website ©MyWebsite.com
{code from clipboard}
</body>
</html>
