Install Millida Launcher

The launcher is free: download it at millida.net/launcher and sign in with any nickname.

Click “Install” on this page

The launcher opens and installs the mod for Minecraft 26.1–26.1.2 on Fabric automatically.

Launch the game

A profile with it appears in the launcher: click “Play”.

Install Fabric

The loader must match the game version of the mod file, for example Minecraft 26.1.2. After installing it, a separate profile appears in your launcher.

Download the file for your version

In the version list above, pick the file simpleblockoverlay-2.0.0+26.1.2-fabric.jar (164 KB) for your game version.

Put it in the mods folder

The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it.

Launch the loader profile

Open “Mods” in the main menu: Simple Block Overlay should be in the list.
