meta name in a non canonical amp html?

Question

I already have a website where :
1. www.example.com ---> is the desktop version (not-amp) 2. www.example.com/mobile ---> is the mobile version (not-amp)

In the index.htm page of the desktop version, I put :

<title>blo blo blo</title>
<meta name="description" content="bla bla bla">
<meta name="keywords" content="blu blu blu">
<link rel="alternate" media="only screen and (max-width: 1024px)"
href="http://www.example.com/mobile/index.php">

<script type="text/javascript">
<!--
if (screen.width <= 1024) {
window.location = "http://www.example.com/mobile/index.php";
}
//-->
</script>

And the index.php page of the mobile version, I put :

<title>blo blo blo</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta name="description" content="bla bla bla">
<meta name="keywords" content="blu blu blu">
<link rel="canonical" href="http://www.example.com/index.htm">

_{Please don't ask me why I have index.htm in desktop version and index.php in mobile version as I myself already forget why I did that a few years ago :).}

Anyway, it works. If I type "www.example.com" in the mobile's browser, then it shows "www.example.com/mobile/index.php" page. If I type "www.example.com" in the desktop's browser, then it shows "www.example.com/index.htm" page.

Now I want to add a new page in a subfolder, but I want to make just one version (which is an amp html page) instead of making two version for the desktop and the mobile.

I read from some articles in the internet that one amp html page is possible meant for both version (desktop and mobile) and from here it say:

AMP HTML files require a canonical link pointing to the regular HTML. If no HTML version exists, it should point to itself.

So, I assume that in this new amp html page in a subfolder, I should put the code something like this :

<link rel="canonical" href="http://www.example.com/jewelry/index.html">

Where that link is pointing to itself (the amp html index page in jewelry subfolder).

What I want here is something like this :

• www.example.com/index.htm (non-Amp, desktop version)
• www.example.com/mobile/index.php (non-Amp, mobile version)
• a new subfolder (named jewelry) with Amp index.htm file. This link will be provided (in a navigation bar) both in example.com/index.htm page and example.com/mobile/index.php page.
• If there are a desktop user and/or a mobile user click that link, he/she will landed to example.com/jewelry/index.htm page (amp version).

I've been looking around in the internet whether I can put a code in amp html page with meta name like below, but I cannot find it:

<meta name="description" content="bla bla bla">
<meta name="keywords" content="blu blu blu">

So, my question is :
Can I put meta name "description" and "keywords" in the amp html page ?

Any kind of respond would be greatly appreciated.
Thank you in advanced.

You need to put meta tag in main file non-amp page and also add the tag to make your page discoverable

<link rel="amphtml" href="http://www.example.com/mobile/index.php">
