Installation

Install

curl -fsSL https://prism.marc27.com/install.sh | bash

This downloads the prebuilt PRISM binary to ~/.prism/bin and adds that directory to your PATH (via ~/.zshrc or ~/.bashrc). macOS (Apple Silicon and Intel) and Linux are supported. Open a new terminal — or source your shell profile — afterward.

To pin a version or change the install location:

PRISM_VERSION=v0.1.0 PRISM_INSTALL_DIR=~/bin \
