-Basically all configuration is done directly inside source code.
+Basically all configuration is done directly inside source code. You
+have to recompile it every time configuration changes. Is it a problem?
+I doubt, because Go is very fast. But it produces huge statically linked
+executables, you say! Use @command{bsdiff}/@command{bspatch}!
+
+Send @code{SIGINFO} signal to get current daemon's configuration.
+
 Initially @command{godlighty} has basic static files handlers (with
 compression, HTTP preconditions are enabled of course). In the example
 below there are nearly all default functions.
