## What it is
bootstrap_form is a Ruby gem that provides a Rails form builder for generating Bootstrap 5-style forms. It augments standard Rails form helpers to automatically produce labels, validation error messages, help text, and all required Bootstrap markup.

## Use cases
- create Bootstrap 5 forms in Rails with less ERB code
- render form fields with labels and validation error messages automatically
- build horizontal Bootstrap forms in a Rails app
- add help text and required-field markup consistently across forms
- migrate Rails forms to Bootstrap 5 styling

## When to choose
- you are building a Rails 7.2+ app with Bootstrap 5 and want clean, maintainable form markup
- you want automatic validation error display and required-field handling without hand-writing Bootstrap classes
- you want to reduce boilerplate in your .erb view files

## When to avoid
- you use Bootstrap 4 or earlier, which this gem does not target
- you don't use Rails or its form helpers
- you need highly custom form markup that fights the gem's generated structure
