The site comes with a very simple default theme by default; you can play around with it, but it's not meant for long-term use. Let's download and install a more interesting theme, notepad.
All versions of the theme can be downloaded from the releases section of the base site repository, here:
Click on the latest release and download the file named like notepad_theme.<version>.dist.zip.
In your site's folder, find the subfolder config/themes. Inside it, create a folder named notepad and extract the contents of the downloaded archive into it. You should end up with two folders: templates and assets there. The final folder structure should look like this:
site
|
config
|
themes
|
bland ← default theme
|
notepad
|
templates
assets
Open the configuration file site/config/site.yaml, find the line:
theme: bland
And change it to:
theme: notepad
Now you can run Mukha in preview mode or generate static files — the new theme should be applied.
