If Homebrew was updated on Aug 10-11th 2016 and brew update always says Already up-to-date. you need to run:

cd "$(brew --repo)" && git fetch && git reset --hard origin/master && brew update

1. Type brew search for a list.
2. Or visit braumeister.org to browse packages online.
3. Or use brew search --desc <keyword> to browse packages from the command line.

brew help, man brew or check our documentation.

First, please run brew update and brew doctor.

Second, read the Troubleshooting Checklist.

If you don't read these it will take us far longer to help you with your problem.

We'd love you to contribute to Homebrew. First, please read our Contribution Guide and Code of Conduct.

We explicitly welcome contributions from people who have never contributed to open-source before: we were all beginners once! We can help build on a partially working pull request with the aim of getting it merged. We are also actively seeking to diversify our contributors and especially welcome contributions from women from all backgrounds and people of colour.

A good starting point for contributing is running brew audit (or brew audit --strict) with some of the packages you use (e.g. brew audit wget if you use wget) and then read through the warnings, try to fix them until brew audit shows no results and submit a pull request. If no formulae you use have warnings you can run brew audit without arguments to have it run on all packages and pick one. Good luck!
