# Releases


CAT has multiple implementations - CAT Studio, PowerShell module, CAT CLI, and there is also Python integration. [How to get started](https://docs.justcat.it/get-started/introduction/ "How to get started?") page can help you choose what tool is best for you.

* **Linux and macOS** — `brew install justcatit/cat/catcli`, or unpack the archive by hand.

Step-by-step instructions for every platform — unpacking the archive, checking the hash, prerequisites, updating and removing — are on the [Installation](https://docs.justcat.it/reference/cat-cli/installation/ "CAT CLI installation") page.
