Text Guides

Rather read than watch? Everything below walks you through it step by step.

Before you start

  1. The Aberration jar isn't released yet — the download will appear on the home page when it is. Everything below is the setup you'll do once you have it.
  2. You do not need to install any other mods — all of Aberration's dependencies are bundled inside the jar.
  3. Jump to your launcher: Quick Import · CurseForge App · Modrinth App · Vanilla Launcher

Quick Import — already use CurseForge or Modrinth?

Sorry — we aren't supported on the CurseForge or Modrinth platforms by default yet, so searching for Aberration there won't find us. In the meantime, these ready-made profile files give you the same one-click setup:

CurseForge App

  1. Download the profile: Aberration-CurseForge.zip (coming soon)
  2. In the app: Minecraft → Create Custom Profile → Import, then pick the downloaded zip.
  3. Hit Play.

Modrinth App

  1. Download the profile: Aberration.mrpack (coming soon)
  2. In the app: click + → Import from file (or just open the .mrpack file).
  3. Hit Play.

Until the profile files are up, follow the manual options below — it only takes a couple more clicks.

Option 1 — CurseForge App

  1. Install the CurseForge App if you don't have it.
  2. Open it, pick Minecraft, and click Create Custom Profile.
  3. Name it (e.g. Aberration), set the game version to 1.21.1, set the mod loader to NeoForge, and create it.
  4. Right-click the new profile → Open Folder, then open the mods folder (create it if it's missing).
  5. Move the downloaded aberration-…-obf-final.jar into mods.
  6. Back in the app, hit Play.

Option 2 — Modrinth App

  1. Install the Modrinth App if you don't have it.
  2. Click Create instance (the + button).
  3. Name it, choose loader NeoForge, game version 1.21.1, and create it.
  4. Open the instance → three-dot menu → Open folder, then open the mods folder.
  5. Move the downloaded aberration-…-obf-final.jar into mods.
  6. Hit Play on the instance.

Option 3 — Vanilla Minecraft Launcher

  1. Go to neoforged.net and download the NeoForge installer version 21.1.225 (for Minecraft 1.21.1).
  2. Run the installer, keep Install client selected, and click OK. It adds a NeoForge profile to your normal Minecraft launcher.
  3. Open your Minecraft folder:
    • Windows: press Win+R, type %appdata%\.minecraft, press Enter.
    • Mac: ~/Library/Application Support/minecraft
    • Linux: ~/.minecraft
  4. Open (or create) the mods folder and move the downloaded aberration-…-obf-final.jar into it.
  5. Open the Minecraft launcher, select the NeoForge profile, and press Play.

Check it worked

On the Minecraft title screen, click Mods — you should see Aberration in the list. If the game won't start or the mod is missing, see the FAQ.

Verify your download (optional)

Every release has a unique fingerprint — a SHA-256 hash — and we'll publish ours alongside the download when the mod goes out. If the fingerprint of your file matches ours, you have the genuine, unmodified jar. If it doesn't match, delete it and download again from this site.

Windows — in PowerShell, from your downloads folder:

Get-FileHash .\latest.jar -Algorithm SHA256

Mac / Linux:

sha256sum latest.jar
