What this needs to run

Cubrim buys its compression ratio with memory, and the download page is the right place to say so. On the published 24-file benchmark, opening the largest archives peaks at 12.3 GiB of resident memory, and creating them peaks at 18.0 GiB. Most files need far less — this is the high-water mark across the whole corpus, and it is what decides whether a machine can handle the worst case.

macOS installer

The `.pkg` installers are signed and notarized for macOS. The normal path is simple: double-click the installer, finish setup, then run `cubrim --version` in Terminal. Use the `.tar.gz` asset only for manual installation. 

sudo installer -pkg cubrim-v0.2.2-macos-apple-silicon.pkg -target /
cubrim --version

Install with Homebrew

Cubrim also ships as a Homebrew tap backed by the same GitHub Release assets. Install it directly with a single command; Homebrew picks the right Apple Silicon, Intel, or Linux tarball for the current machine. 

brew install arcanada-one/cubrim/cubrim

Homebrew installs `cubrim` onto PATH automatically. After install, run `cubrim --version`.
