# Interesting Taps and Forks

A [tap](Taps.md) is Homebrew-speak for a Git repository containing additional formulae.

Homebrew has the capability to add (and remove) multiple taps to your local installation with the `brew tap` and `brew untap` commands; run `man brew` in your terminal for usage information.

Your taps are Git repositories located at `$(brew --repository)/Library/Taps`. As a normal user, you usually won't see `homebrew/core` here anymore and that's OK - [normal usage is via the JSON API](https://brew.sh/2023/02/16/homebrew-4.0.0/).

The taps and forks below are third-party repositories that are not maintained, reviewed or trusted by Homebrew.
Tapping or installing from them runs their code with your user's privileges, so only add ones you trust.
See [Tap Trust](Tap-Trust.md) for how to trust only the specific formula, cask or command you need and [Software Supply Chain Security](Homebrew-Security-and-Supply-Chain.md) for why this matters.
