The Rails add-on is a Ruby LSP add-on for extra Rails editor features.
If you haven't already done so, you'll need to first set up Ruby LSP.
As of v0.3.0, Ruby LSP will automatically include the Ruby LSP Rails add-on in its custom bundle when a Rails app is detected. There is no need to add the gem to your bundle.
See the documentation for more in-depth details about the supported features.
See CONTRIBUTING.md
