Could you provide some default/preconfigured settings?

I don't know how to setup :( I have tried this one but I didn't see the wind animation:

config = function ()
  require('wlsample.wind')
end

Could it be something like this?

config = function ()
  require('windline').setup {
    predefined: 'some_cool_default'
  }
end

you can type in command :lua require('wlsample.airline_anim')

I don't know how to put the section you linked into the require('windline').setup { ... }. And it seems that if I provide nothing to the ... I will get error during plugin-installation of packer.nvim

you dont' need to use setup function just require a sample statusline.

if you want to modify it. You need copy sample config to your nvim config folder and modify it.

OK cool. Most of the plugins tolding me to call the setup { ... } after installation. So I don't have to add the config = function() ... end field in my packer.nvim settings?

it have a setup function but it has too many line so i create a new file.
