Installing an Origin CA - Documentation is not clear

I am trying to follow this tutorial of creating an Origin CA:

On Step 2 - Install an Origin CA certificate at your origin web server, I got confused.
Step2.1 - Upload the Origin CA certificate - OK.
Step2.2 - Use the linked installation guides below to update your web server configuration to point to the certificate - Not Clear to me.
For me it’s Nginx and this the link https://www.digicert.com/csr-ssl-installation/nginx-openssl.htm#ssl_certificate_install.

So after step 1 I have on my server 2 files:

/etc/ssl/example.co.il.pem;
/etc/ssl/example.co.il.key;

So I am at:

II. Nginx: Installing & Configuring Your SSL Certificate

What do I need to do here?
should I click on Creating Your CSR with OpenSSL?

I think not, that’s what I did in Step 1,
So I go forward from there to:

How to Install and Configure Your SSL Certificate

Primary and intermediate certificates

  1. You should’ve received a your_domain_name.pem file from DigiCert in an email when your certificate was issued. This .pem file contains both your primary certificate and the intermediate certificate. If you have that .pem file, you can skip to step 4.
  2. If you need to concatenate your primary certificate and your intermediate certificate in to a single file, see step 2.

So I didn’t receive anything from DigiCert and I have 2 files, not a concatenate one
And on section 2 it asks:

If you need to concatenate your primary certificate and your intermediate certificate in to a single file, see step 2.

Do I need to concatenate those files? I don’t know…

And most instructions there are not related at all to Cloudflare result I got from Step 1 of the cloudflare tutorial.

Does Cloudflare want me to create an account at DigiCert? I don’t understand what do I need to do next…

Maybe just create a normal youtube tutorial instead of complicating this issue!
