In order to rebuild the application you need to install all dependencies first. To do it, open the terminal in the project directory and type:
npm install
Make sure that you have the node and npm installed first. If not, then follow the instructions on the Node.js documentation page.
Now you can install additional plugin in the build. Just follow the Adding a plugin to an editor tutorial
If you have already done the Installation and Adding or removing plugins steps, you're ready to rebuild the editor by running the following command:
npm run build
This will build the CKEditor 5 to the build directory. You can open your browser and you should be able to see the changes you've made in the code. If not, then try to refresh also the browser cache by typing Ctrl + R or Cmd + R depending on your system.
Follow the guides available on https://ckeditor.com/docs/ckeditor5/latest/framework/index.html and enjoy the document editing.
