 ## Custom event scripts
 
-There are numerous locations throughout ES-DE where custom scripts will be executed if the option to do so has been enabled in the settings. You'll find the option on the Main menu under `Other settings`. By default it's deactivated so be sure to enable it to use this feature.

 We'll go through two examples:
 * Creating a log file that will record the start and end time for each game we play, letting us see how much time we spend on retro-gaming
 * Changing the system resolution when launching and returning from a game in order to run the emulator at a lower resolution than ES-DE
 
-The following examples are for Unix systems, but it works the same way on macOS (which is also Unix after all), and on Windows (although .bat batch files are then used instead of shell scripts and any spaces in the parameters are not escaped as is the case on Unix).

-The events executed when a game starts and ends are named `game-start` and `game-end` respectively. Finding these event names is easily achieved by starting ES-DE with the `--debug` flag. If this is done, all attempts to execute custom event scripts will be logged to es_log.txt, including the event names.
+As can be seen in the table above, the events executed when a game starts and ends are named _game-start_ and _game-end_
 
 So let's create the folders for these events in the scripts directory. The location is `~/.emulationstation/scripts`
