+# This is a custom nginx configuration file that we use in the container (instead of the default one),
+# because it allows us to run nginx with a non-root user.
+#
+# For this to work, the default vhost file (`/etc/nginx/conf.d/default.conf`) also needs to be removed.
+# (mounting `/dev/null` over `/etc/nginx/conf.d/default.conf` works well)
+#
+# The following changes have been done compared to a default nginx configuration file:
+# - default server port is changed (80 -> 8080), so that a non-root user can bind it
+# - various temp paths are changed to `/tmp`, so that a non-root user can write to them
+# - the `user` directive was removed, as we don't want nginx to switch users
