# Homebrew Core Core formulae for the Homebrew package manager. ## Update Bug If Homebrew was updated on Aug 10-11th 2016 and `brew update` always says `Already up-to-date.` you need to run: ```bash cd $(brew --repo); git fetch; git reset --hard origin/master; brew update ``` ## How do I install these formulae? Just `brew install `. This is the default tap for Homebrew and is installed by default. ## Troubleshooting First, please run `brew update` (twice) and `brew doctor`. Second, read the [Troubleshooting Checklist](https://github.com/Homebrew/brew/blob/master/share/doc/homebrew/Troubleshooting.md#troubleshooting). **If you don’t read these it will take us far longer to help you with your problem.** ## Contributing Read [CONTRIBUTING.md](/.github/CONTRIBUTING.md). Creating new formulae, updating existing ones, and fixing build issues is easier than you think! Try `brew edit $FORMULA` and see how you fare. ## Documentation `brew help`, `man brew`, [Homebrew/brew's README](https://github.com/Homebrew/brew#homebrew) or check [Homebrew's documentation](https://github.com/Homebrew/brew/tree/master/share/doc/homebrew#readme). ## License Code is under the [BSD 2 Clause (NetBSD) license](https://github.com/Homebrew/homebrew-core/blob/master/LICENSE.txt).
