Suggested change

	- An active F5 WAF for NGINX subscription. Available from [MyF5](https://my.f5.com/manage/s/) (purchased or trial).
	- Download the [SSL certificate and private key file]({{< ref "/waf/install/docker.md#General subscription credentials needed for deployments" >}}) associated with your F5 WAF for NGINX WAF subscription from the MyF5 Customer Portal if you are using NGINX Open Source in your deployment.
	- Download the [SSL certificate and private key file]({{< ref "/waf/install/docker.md#General subscription credentials needed for deployments" >}}), and the [JWT license file]({{< ref "/waf/install/docker.md#Additional subscription credentials needed for deployments" >}}) associated with your F5 WAF for NGINX subscription from the MyF5 Customer Portal if you are using NGINX Plus in your deployment.
	- An active F5 WAF for NGINX subscription. Available from [MyF5](https://my.f5.com/manage/s/) (Purchased or trial).

Hyperlinking a later section could cause the reader to skip additional important context in this section.

The instructions with the links are also redundant: there's no point linking to the same place twice.

The majority of readers will be reading the page sequentially from top to bottom, so there is no need to add extra emphasis to a requirement you will be giving them instructions to fulfill anyway.

Suggested change

	## Download your subscription credentials
	### General subscription credentials needed for deployments
	{{< include "licensing-and-reporting/download-certificates-from-myf5.md" >}}
	### Additional subscription credentials needed for deployments
	To use NGINX Plus and access private-registry.nginx.com, you will need to download the the JWT license file associated with your F5 WAF for NGINX WAF subscription from the [MyF5](https://my.f5.com/manage/s/) Customer Portal:
	{{< include "licensing-and-reporting/download-jwt-from-myf5.md" >}}
	## Download your subscription credentials
	### General subscription credentials needed for deployments
	{{< include "licensing-and-reporting/download-certificates-from-myf5.md" >}}
	### Additional subscription credentials needed for deployments
	To use NGINX Plus and access private-registry.nginx.com, you will need to download the the JWT license file associated with your F5 WAF for NGINX WAF subscription from the [MyF5](https://my.f5.com/manage/s/) Customer Portal:
	{{< include "licensing-and-reporting/download-jwt-from-myf5.md" >}}

All headings are meant to be surrounded by blank lines, which are detected by the linting tools on this branch, which can be executed automatically with pre-commit.

These requirements will be directly enforced by CI/CD in the future, so I recommend you begin using these tools.
