# Install the CLI and type rivr

The CLI no longer has to be run as `node rivr.mjs`. On macOS and Linux, `curl -fsSL https://developers.rivr.io/cli/install.sh | sh` installs it; on Windows, `irm https://developers.rivr.io/cli/install.ps1 | iex` in PowerShell. Both check that Node.js 18 or later is installed, put the CLI in ~/.rivr/bin with a `rivr` command, and refuse a downloaded file whose SHA-256 is not the one the portal serves. Neither needs administrator rights. The Windows script puts the folder on your user PATH; the macOS and Linux script never edits your shell's startup files and prints the line to add instead. If another `rivr` is already on your PATH, the command is called `rivrdev`; `RIVR_CLI_NAME` chooses the name and `RIVR_INSTALL` the folder. Run the same command again to update. `node rivr.mjs` keeps working.
