 #### Simplified debugging instructions (when `FTL` is running)
 
-`FTL` has been designed such that a debugger can be attached to an already running process to ease debugging. Use `sudo gdb -p $(cat /var/run/pihole-FTL.pid)` to attach to the already running `pihole-FTL` process. You can leave off `sudo` if you are running `pihole-FTL` with the current user. Once loading of the symbols has finished (the `(gdb)` input prompt is shown), run `continue` to continue operation of `pihole-FTL` inside the debugger. All debugger features are now available.

 If `pihole-FTL` has crashed, copy&paste the terminal output into a (new) issue. Also type `backtrace` and include its output. We might ask for additional information in order to isolate your particular issue.
