+Just throwing that out there because I cannot seem to remember that.  Once upon a time, I had the same struggles with Steely Dan and Supertramp.  I'm detecting a pattern.
 ==== Creating header images for the web site ====

 I download the text image to my PC and then head to https://pixlr.com/editor, where I load the graphic image and then open a new layer and select the text image that goes over top the graphic image.  I’m still not the best at moving it around; it’s a work in progress.  I save the combined image to my PC and then upload it to the web site for use.
+==== NGINX Maintenance ====
+After repeated cycles of creating and deleting proxy hosts over the course of time, I found that I had lingering cert configurations that were no longer valid.  I.E., I'd delete the proxy host, the cert would be allowed to expire, but for whatever reason NGINX would continue to try to renew it.  This generated a crap ton of error logs and even got me throttled by LetsEncrypt for a while due to repeated invalid requests.
+I finally was able to clean up the configurations by poring through them and removing what was stale.  What follows is an overview of the process.
+Get into a bash prompt within the docker container and execute the **certbot certificates** command.  Either pipe it through **more** or scroll up through the output to review the list of all certs known in the system.
+Certs can also be viewed individually by way of the following command syntax example:
+  certbot certificates --cert-name npm-20
+If it is then found that this particular cert is no longer needed, it can be removed with the following command example:
+  certbot delete --cert-name npm-20
