+# Modified based on Squid OCI image entrypoint
+
+# This entrypoint aims to forward the squid logs to stdout to assist users of
+# common container related tooling (e.g., kubernetes, docker-compose, etc) to
+# access the service logs.
+
+# Moreover, it invokes the squid binary, leaving all the desired parameters to
+# be provided by the "command" passed to the spawned container. If no command
+# is provided by the user, the default behavior (as per the CMD statement in
+# the Dockerfile) will be to use Ubuntu's default configuration [1] and run
+# squid with the "-NYC" options to mimic the behavior of the Ubuntu provided
+# systemd unit.
+
+# [1] The default configuration is changed in the Dockerfile to allow local
+# network connections. See the Dockerfile for further information.
