Homebrew was formerly referred to as Linuxbrew when running on Linux or WSL. It can be installed in your home directory, in which case it does not use *sudo*.

Homebrew can install its own current versions of *glibc* and *gcc* for older distributions of Linux.

 Instructions for the best, supported install of Homebrew on Linux are on the [homepage](https://brew.sh).
 
-The installation script installs Homebrew to `/home/linuxbrew/.linuxbrew` using *sudo* if possible and within your home directory at `~/.linuxbrew` otherwise. Homebrew does not use *sudo* after installation. Using `/home/linuxbrew/.linuxbrew` allows the use of most binary packages (bottles) which will not work when installing in e.g. your personal home directory.

 Technically, you can install Homebrew wherever you want. However, you shouldn't install outside the default, supported, best prefix. Many things will need to be built from source outside the default prefix. Building from source is slow, energy-inefficient, buggy and unsupported. The main reason Homebrew just works is **because** we use bottles (binary packages) and most of these require using the default prefix. If you decide to use another prefix: don't open any issues, even if you think they are unrelated to your prefix choice. They will be closed without response.
