+### LightningCAD
+
+For LightningCAD apps there are [generators](./lib/generators/lightning_cad) to add the required setup
+
 ## Development
 
 Install the versions of Node and Ruby specified in `.node-version` and `.ruby-version` on your machine. https://asdf-vm.com/ is a great tool for managing language versions. Then run `npm install -g yarn`.

+# LightningCAD Generator
+
+Run all the generators:
+
+```
+rails g lightning_cad:all
+```
+
+Or run them individually
+```
+rails g lightning_cad:install
+rails g lightning_cad:webpack
+rails g lightning_cad:test
+```
+
+## Depends On
+
+- `rolemodel:linters:eslint`
+- `rolemodel:optics:base`
+- `rolemodel:webpack`
+- `rolemodel:react`
+
+## What you get
+
+Pulls in [LightningCAD](https://github.com/RoleModel/lightning-cad) and sets up a demo editor
+
+This will add a route for `/editor` with a blank canvas.
+
+The main entrypoint into the JavaScript code is `/app/javascript/components/App.jsx`. In this file a project is created. You can manually add components like lines or shapes to that project.
+
+After running the generators additional setup is required see [how to setup a LightningCAD app](https://github.com/RoleModel/lightning-cad?tab=readme-ov-file#app-setup) for more details.

+Description:
+    This generator requires JavaScript setup including webpack, react, and eslint
+
+    Install:
+        Installs required dependencies
+        Generates a demo editor
+
+    Webpack:
+        Modifies the webpack config to work better for LightningCAD apps
+
+    Test:
+        Installs jasmine and adds the test setup required for LightningCAD models
+
+Example:
+    bin/rails generate lightning-cad:all
