4. Inside the frontend-app-course-authoring folder clone this repository and checkout to this branch.

5. Inside the frontend-app-course-authoring folder create a new file called module.config.js with this content:

   module.exports = {
     localModules: [
       {
         moduleName: "@edx/frontend-lib-content-components/dist",
         dir: "./frontend-lib-content-components",
