+HTTPD_NGINX_WORKER_PROCESSES
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Defines the number of worker processes for Nginx, i.e, the number of CPU cores.
+
+The optimal value depends on many factors including (but not limited to) the number of CPU cores,
+the number of hard disk drives that store data, and load pattern. When one is in doubt, setting it
+to the number of available CPU cores would be a good start
+(the value “auto” will try to autodetect it).

+
+HTTPD_NGINX_WORKER_CONNECTIONS
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Sets the maximum number of simultaneous connections that can be opened by a worker process.
+
+It should be kept in mind that this number includes all connections (e.g. connections with proxied
+servers, among others), not only connections with clients. Another consideration is that the actual
+number of simultaneous connections cannot exceed the current limit on the maximum number of open
+files, which can be changed by worker_rlimit_nofile.
