1. Find the formula for the version you want to install:

   • Visit https://github.com/Homebrew/homebrew-core/tree/master/Formula
   • Click the file with your formula (e.g. “composer.rb”)
   • Click “History” (top right)
   • Click the commit hash for the version you want to download
   • Click the three dots (top right of diff) and choose “view file”
   • Click “Raw” and copy the raw URL from the browser address bar.
