If you are using FoamFix Anarchy Version, disable B:initOptions in the FoamFix config or else Default Options will not work. See https://github.com/blay09/DefaultOptions/issues/25 for more info.

Setting up Default Keys

1. Configure the keys how you'd like them to be in the default configuration
2. Run the "/defaultoptions saveKeys" command: the file defaultkeys.txt will be saved in the config folder
3. Make sure to ship the defaultoptions folder inside the config directory, and NOT the options.txt from the root directory in your modpack. Victory!

Check the Controls GUI to see that the default settings have updated. Players will now start with these keys by default.

Setting up Default Options

1. Configure the options (e.g. FOV, video and audio settings) how you'd like them to be in the default configuration
2. Run the "/defaultoptions saveOptions" command: the file defaultoptions.txt will be saved in the config folder
3. Make sure to ship the defaultoptions folder inside the config directory, and NOT the options.txt from the root directory in your modpack. Woohoo!

Fresh installations of your pack (=> no existing options.txt) will now get the default options you specified.

Setting up Default Servers (Minecraft 1.9.4+)

1. Set up the servers how you'd like them to be in new installations
2. Run the "/defaultoptions saveServers" command: the file servers.dat will be copied into the defaultoptions folder
3. Make sure to ship the defaultoptions folder inside the config directory, and NOT the servers.dat from the root directory in your modpack. Victory!

Setting up Default Configs (Minecraft 1.9.4+)

If you want to set up your modpack in a way that lets users change specific config files without having them overwritten by updates, you can put those files into the defaultoptions folder rather than the config folder. Those files will only be copied over into the config folder on the first run of the pack. Sadly Minecraft's mod configurations aren't standardized enough to provide a more complex solution without having lots of breakage.
