[Doc] Installation documentation could mention the step for adding shadcn css and helper dependencies

[peterberkenbosch]

PR incoming, wanted to share my findings here and start discussion on how to improve wording.

When reading the installation docs, it's mentioning that the shadcn.css is installed. This is only done when you run the generator for a component though.

#> bin/rails g shadcn-ui
Checking for tailwind...
...tailwind found.
Checking for shadcn.css...
...copying shadcn.css to app/assets/stylesheets/shadcn.css
Checking for shadcn import...
Importing shadcn.css into application.tailwind.css...
Checking for shadcn.tailwind.js...
...copying shadcn.tailwind.js to config/shadcn.tailwind.js
Make sure to include shadcn.tailwind.js in your tailwind.config.js
const shadcnConfig = require('./shadcn.tailwind.js');
module.exports = {
  ...shadcnConfig,
};
Checking for component_helper.rb
...copying components_helper.rb app/helpers
rails generate shadcn-ui <component_name> [--remove] [rails_root_path]
....

How about adding an install generator that does the setup listed above?

The generator that does the setup instead on install instead of with every component, makes total sense.

I got hung up on this as well - it wasn't clear what step to take to generate shadcn.css (maybe I missed something obvious somewhere)

Thanks for raising this issue. I was stuck at the same spot and if not this issue would have simply abandoned. 🙏 🌮

@peterberkenbosch it's a great idea! I was stuck at the same spot, and this issue helped.

@peterberkenbosch I would be happy to contribute to this. Can I take this up?

Well, you say that, but how do people know? We are now in 2025, I tried to use this for the first time. And there is no mention of this in the installation instructions. I've got live reload enabled, errors immediately appear of not finding this css file. The IDE is complaining as well. And no indication in the setup that you have to do this.

Love the project, love the work, but surely this should be included.
