In addition to Custom Main Menu Mod 1.12.2/1.10.2/1.7.10 is possible to add or remove buttons and labels, it is also possible to add some new content that you can add to your main menu. It includes slideshows or full custom guis.
However, simple things like adding or changing some text are a small feature of this mod. You will notice an additional button added to your main menu. That is the difference you should notice after the first run.
You should see a file called menu.json if you look in the config/CustomMainMenu folder. In it, it will include the main elements that the vanilla menu has. If you modify the content, you can immediately see the changes you have made by pressing the refresh button in Minecraft. If you are satisfied with your result, you can remove the refresh button. And if you have worked with JSON file before, you will find everything in it really easy to understand.
