This is a by-OS breakdown of how you can install the software on your machine.
As LRR is a server app first and foremost, its setup is a bit more complex than your usual Desktop application.
However, a lot of work as been done behind the scenes to make it easy!
Look at the methods below for something that fits your OS and usage.
Linux/macOS: Homebrew
Homebrew allows you to quickly setup LRR on macOS and Linux without relying on containers or modifying your preinstalled system libaries.
Taking a page from sysadmin books, you can easily install LRR as a container with Docker.
They're lightweight, easy to update, and automatically built/tested. I recommend this for NAS setups!
