# Interesting Taps & Forks
A _tap_ is homebrew-speak for a Git repository containing extra formulae.
-Homebrew has the capability to add (and remove) multiple taps to your local installation with the `brew tap` and `brew untap` commands. Type `man brew` in your Terminal. The main repository <https://github.com/Homebrew/homebrew-core>, often called `homebrew/core`, is always built-in.
+Homebrew has the capability to add (and remove) multiple taps to your local installation with the `brew tap` and `brew untap` commands. Type `man brew` in your Terminal. The main repository [https://github.com/Homebrew/homebrew-core](https://github.com/Homebrew/homebrew-core), often called `homebrew/core`, is always built-in.
## Main taps
* [homebrew/apache](https://github.com/Homebrew/homebrew-apache): A tap for Apache modules, extending macOS's built-in Apache. These brews may require unconventional additional setup, as explained in the caveats.
-* [homebrew/boneyard](https://github.com/Homebrew/homebrew-boneyard): Formulae from other official taps, primarily `homebrew/core` are not deleted, they are moved here.
-
-* [homebrew/bundle](https://github.com/Homebrew/homebrew-bundle): Bundler for non-Ruby dependencies from Homebrew.
-
-* [homebrew/completions](https://github.com/Homebrew/homebrew-completions): Shell completion formulae.
-
-* [homebrew/dupes](https://github.com/Homebrew/homebrew-dupes): Need GDB or a newer Tk? System duplicates go here.
-
-* [homebrew/emacs](https://github.com/Homebrew/homebrew-emacs): A tap for Emacs packages.
-
-* [homebrew/games](https://github.com/Homebrew/homebrew-games): Game or gaming-emulation related formulae.
-
* [homebrew/nginx](https://github.com/Homebrew/homebrew-nginx): Feature rich Nginx tap for modules.
* [homebrew/php](https://github.com/Homebrew/homebrew-php): Repository for php-related formulae.
-* [homebrew/python](https://github.com/Homebrew/homebrew-python): A few Python formulae that do not build well with `pip` alone.
-
* [homebrew/science](https://github.com/Homebrew/homebrew-science): A collection of scientific libraries and tools.
-* [homebrew/services](https://github.com/Homebrew/homebrew-services): A tool to start Homebrew formulae's plists with `launchctl`.
-
-* [homebrew/x11](https://github.com/Homebrew/homebrew-x11): Formulae with hard X11 dependencies.
-
-`brew search` looks in these main taps as well as in [homebrew/core](https://github.com/Homebrew/homebrew-core). So don't worry about missing stuff. We will add other taps to the search as they become well maintained and popular.
