Every build with its requirements, changelog and SHA-256 checksum.
Upcoming installer versions bundle only the mod, Fabric Loader and Fabric API and download optional mods and shaders (Sodium, Iris, Complementary Reimagined, Rethinking Voxels) from Modrinth during installation; this needs an internet connection.

- Easiest way on Windows: run the installer, pick what you want (performance and shaders are optional) and choose your Minecraft folder. Then start the official Minecraft Launcher and select the profile "The Astral Sea". Windows may warn about an unknown publisher because the installer is not signed; click "More info" and "Run anyway".
- Using the Modrinth App or Prism Launcher instead: download the modpack and open the .mrpack file. It sets up Minecraft 1.21.1 with Fabric, Fabric API, Sodium, Iris, The Astral Sea and the Complementary Reimagined shader in its own instance.
- Pre-alpha: unfinished, unbalanced and not ready for survival worlds. Back up your world before trying it.
- Requires Fabric Loader 0.19.5 or newer and Fabric API (0.116.17+1.21.1). Iris and Sodium are optional; shaders such as Complementary Reimagined and Rethinking Voxels are supported.
- There is no portal yet. In a world with cheats enabled, use /astralsea tp to enter the dimension. Falling into the Astral Sea takes you back to the Overworld, the Nether or the End.
