Theme not working without `brand` parameter being set

[WortPixel]

When trying to follow the installation instructions from the README the theme won't work unless the parameter brand is set. Not setting it results in an error pointing to the partials/head/meta.html, where $.Site.Params.brand is called without a default value.

Tested with hugo v0.135.0.

Suggested solutions:

• Adapt README.md to include hint to set brand parameter. Meanwhile adding a hint, that hugo nowadays calls the config hugo.toml instead of config.toml might also be helpful for some users.

# hugo.toml
[params]
    brand = 'MyBrand'

• Add default value handling to the given position in the meta.html.

Thanks for the theme!
