Inside the new assets folder, create another new folder with the same name as your mod id. For example, my folder would be called 'examplecontentmod', as this is my mod id. Similar to your mod id, domains must be lowercase. This new folder is where your mod assets will be created! If a tutorial refers to your 'mod assets' folder, it is likely referring to this folder.
