 ### Or add @eeacms/volto-plotlycharts to your Volto project
 
-Before starting make sure your development environment is properly set. See [Volto Developer Documentation](https://docs.voltocms.com/getting-started/install/)
+Before starting make sure your development environment is properly set. See the official Plone documentation for [creating a project with Cookieplone](https://6.docs.plone.org/install/create-project-cookieplone.html) and [installing an add-on in development mode in Volto 18 and 19](https://6.docs.plone.org/volto/development/add-ons/install-an-add-on-dev-18.html).
 
-1.  Make sure you have installed `yo`, `@plone/generator-volto` and `mrs-developer`
+For new Volto 18+ projects, use Cookieplone. It includes `mrs-developer` by default.
 
-        npm install -g yo @plone/generator-volto mrs-developer
+1.  Create a new Volto project with Cookieplone
 
-1.  Create new volto app

-        yo @plone/volto my-volto-project --addon @eeacms/volto-plotlycharts --skip-install
-        cd my-volto-project
+        uvx cookieplone project
+        cd project-title
 
 1.  Add the following to `mrs.developer.json`:
 
         {
             "volto-plotlycharts": {
+                "output": "packages",

                 "path": "src"
             }
         }
 
-1.  Install
+1.  Add `@eeacms/volto-plotlycharts` to the `addons` key in your project `volto.config.js`
+
+1.  Install or refresh the project setup
 
-        make develop
-        yarn
+        make install
 
-1.  Start backend
+1.  Start backend in one terminal
 
-        docker run --pull always -it --rm --name plone -p 8080:8080 -e SITE=Plone plone/plone-backend
+        make backend-start
 
-    ...wait for backend to setup and start - `Ready to handle requests`:
+    ...wait for backend to setup and start, ending with `Ready to handle requests`
 
     ...you can also check http://localhost:8080/Plone
 
-1.  Start frontend
