+#### Apps using tailwind
+
+If you use tailwind with the basic install, you need to edit the tailwind config.
+
+Basically it is impossible to have two tailwind generated stylesheets, so your app needs to pick
+up the merged styles. This can be configured like so:
 
 ```
-corePlugins: {
-  preflight: false,
-}
+const output = execSync('bundle show merged', { encoding: 'utf-8' });
+const fullname = output.trim() + '/app/**/*.{haml,html,rb}' ;
+
+
+module.exports = {
+  content: [
+    fullname ,
+    .... as before
+  ]
 ```
 
+## Developers
+
+### Styles
+
+Developers should look at the predefined styles. These are found in
+merged gem /config/merged/**style.yml
+
+And on a running app http://localhost:3000/merged/styles/index
+
+### Section Views
+
+These are under app/views/merged/views/sections/*haml
+and the name of the file matches the section_style entry
+
+Developers may define more section styles, but must provide the partials to render them.
+
+### Card Views
+
+These are under app/views/merged/views/cards/*haml
+and the name of the file matches the card entry.
+
+Developers may define more card styles, but must provide the partials to render them.
+
+### Options
+
+Option definitions (also found under style dir) are common between elements.
+Options may be added and then used in the view partials. Many common ones (background,
+color) and many more are already defined.
+
+To make the partials more dry, Helpers are defined in OptionsHelper
