+### NeoForge
+Works almost the same way as Forge, but you need to use `NeoForgeVersion` instead of `ForgeVersion` and `NeoForgeVersionBuilder` instead of `ForgeVersionBuilder`.
+Be careful when passing the neoforge version, it must be in the forge format for 1.20.1 (1.20.1-47.1.5 for example) ; but you should only pass the neoforge version for versions >= 1.21 (21.8.31 for example).

+            .withFileDeleter(new ModFileDeleter("sodium.jar")) // (optional but recommended) delete bad mods ; but it won't remove the file sodium.jar if it's present in the mods' dir.
