What you were trying to do (and why)

Trying to install Homebrew on a Mac with an M2 chip. I wanted to use Homebrew to manage packages and utilities on my Mac.

What happened (include command output)

When trying to install Homebrew, I encountered the following warning message:

Warning: /opt/homebrew/bin is not in your PATH.

~ % brew  
zsh: command not found: brew

To resolve this issue, I manually added export PATH=/opt/homebrew/bin:$PATH to my ~/.zshrc file:

This is expected behaviour and what the installer tells you to do.
