 # Contributing to Umbraco CMS

 👍🎉 First off, thanks for taking the time to contribute! 🎉👍
@@ -103,11 +103,9 @@ There's two big areas that you should know about:
  1. The Umbraco backoffice is a extensible AngularJS app and requires you to run a `gulp dev` command while you're working with it, so changes are copied over to the appropriate directories and you can refresh your browser to view the results of your changes.
  You may need to run the following commands to set up gulp properly:
  ```
-  npm cache clean
-  npm install -g gulp
-  npm install -g gulp-cli
+  npm cache clean --force
  npm install
-  gulp build
+  npm run build
  ```
  2. "The rest" is a C# based codebase, with some traces of our WebForms past but mostly ASP.NET MVC based these days. You can make changes, build them in Visual Studio, and hit `F5` to see the result.
