- You MUST NOT try and generate a Rails app from scratch on your own by generating each file. For a NEW app you MUST use
rails new
first to generate all of the boilerplate files necessary. - Create an app in the current directory with
rails new .
- Use Tailwind CSS for styling. Use
--css tailwind
as an option on therails new
call to do this automatically. - Use Ruby 3.2+ and Rails 8.0+ practices.

If you encounter a problem where you cannot commit changes in Git – neither through the terminal nor via the GitHub Desktop application – the issue might be a freeze during the Git commit process. This is often caused by GPG lock issues. Below is a concise and step-by-step guide to resolve this problem.
Open your terminal and try to perform a GPG operation (like signing a test message). If you see repeated messages like gpg: waiting for lock (held by [process_id]) ...
, it indicates a lock issue.
