Forge vs Fabric in one minute

	Fabric	Forge
Strength	Light, fast updates, many performance mods	Large content mods and classic modpacks
Good on weak phones?	Usually better	Depends on the pack
Needs a helper mod?	Most mods need Fabric API	Rarely

Install steps

Pick a game version. Choose the Minecraft version your mods support. Check the mod page first, versions must match exactly.
Get the installer. Download the official Forge or Fabric installer .jar for that version to your device.
Run the installer in MojoLauncher. Use the launcher's option to run a .jar installer and select the downloaded file.
Complete the installer. Choose client installation and finish. A new version entry appears in the launcher.
Add mods. Copy compatible mod .jar files into the mods folder of your game directory.
Launch. Select the Forge or Fabric version and press Play.

Menu names can change between releases. If a label differs, look for the launcher's "install .jar / modloader" option.

Importing modpacks

Since the Iris release you can import local Modrinth .mrpack and CurseForge .zip modpacks directly in the launcher. Download the pack file first, then import it. The launcher creates an instance with the right version.

Tips for modded play

Match the mod loader, Minecraft version and mod versions exactly.
Allocate more RAM for large packs, but leave memory for Android.
Shader-heavy mods may need the LTW renderer; Angelica, Create: Aeronautics and GregTech: New Horizons received fixes in Iris.
Add mods one at a time to isolate crashes.
Only download mods from reputable sites like Modrinth and CurseForge.

Troubleshooting

Crash on start: remove mods in halves until it launches.
Missing dependency: the crash message names the library you need.
Graphics glitches: switch renderer, see best settings.

FAQ

Forge or Fabric: which should I choose?

Pick the loader your mods or modpack need. Fabric is common for lightweight and performance mods; Forge for many large content mods.

Why does my game crash after adding a mod?

Usually a version or loader mismatch, or a missing dependency such as Fabric API. Remove mods in halves to find the cause.

Can I import a modpack?

Yes. Local Modrinth .mrpack and CurseForge .zip packs can be imported.
