Introduction

Zehn offers a lot of settings to match Windows 10 options and offer some personalization of your Steam as well.

Millennium

If you are using Millennium, you can configure Zehn via the integrated Library Manager. If you wish to override certain variables, use Quick CSS.

SFP

If you are using SFP, you can configure Zehn by editing the ~/config/options.json. The rest of this guide is specifically to help you know what the options are when using SFP.

You may use ~/custom.css to override any variables from ~/css/variables.css. Some special colors that are editable via GUI in Millennium may be found in ~/config/colors.css to edit.

The default config. One important step you must do if using SFP is to set enable to true! Otherwise, this config will be ignored. Be sure to have this set to false if you are using Millennium, otherwise you will have everything patched twice!
