# Installation Instructions for Mac OS X

You can use our Homebrew tap to install pchain. If you don't have Homebrew, [install it first](https://brew.sh/)

Then run the following commands to add the tap and install `pchain`:

```
brew tap pchain-org/pchain
brew install pchain
```

Upgrade the latest version of 'pchain'

```
brew upgrade pchain
```

You should now be able to check the different options and commands with 'pchain --help'.
