--- In case you don't wanna have errors:
-
--- Only change what's behind a "=" (or "--"). 
--- Don't use caps (behind a "=").
-
--- If there's a "false" (behind a "=") you can change it to "true" (and the other way around).
--- Spelling is important.
--- If "true" or "false" is necessary as setting, everything(!) which is not spelled "true" will be read as if it were "false" (even "1", "True"...)
-
--- If you wanna comment something (for example to remember the default value), you can do this by putting "--" in front of the comment.
--- You can put "--" at the end of a line with "=" in it, or at the beginning of an empty/new line (minetest will ignore what's behind it then).
--- But don't put "--" in front of a line with "=" in it (or else minetest will ignore the setting and you might get an error).
