Install

With the installer (macOS and Linux)

curl -fsSL https://raw.githubusercontent.com/iAmLakshya/simstim/main/install.sh | sh

It downloads the release for your system, checks its signature with ssh-keygen and its SHA-256, and installs into ~/.local/bin. It changes nothing else. Options, as environment variables:

Variable	Does
`INSTALL_DIR`	Install somewhere else
`VERSION`	A release tag, such as `v0.1.0`, instead of the latest

With Go

go install github.com/iAmLakshya/simstim@latest

A client built this way has no host helpers inside it. The first time it connects a host, it downloads the helper bundle of its own release, checks the release’s signature with ssh-keygen and the bundle’s SHA-256, and keeps it in ~/.cache/simstim/helpers/. Set SIMSTIM_RELEASES_URL to fetch from a mirror instead.

With Homebrew

The tap opens with the first public release.

From source

git clone https://github.com/iAmLakshya/simstim
cd simstim
scripts/setup.sh
just build

The client is bin/simstim.

Check a release by hand

Releasing shows the three ways: the SSH signature, the cosign bundle and the GitHub attestation.

Update

Run the installer again. The next time the client connects to a host, it installs the matching helper beside the old one; sessions that are running keep the helper they started with.
