 ## Installation
 
-Currently you can install Lula a couple different ways. A brew formulae is in the plan, but not currently implemented. Lula is currently only compatible with Linux/MacOS distributions.
+Currently, you can install Lula in a couple of different ways: using Homebrew or from source. Lula is compatible only with Linux and macOS distributions.
+
+### Homebrew
+
+1) [Homebrew](https://brew.sh/) is a package manager for macOS and Linux. You can install Lula with Homebrew by running the following:
+
+    ```shell
+    brew tap defenseunicorns/tap && brew install lula
+    ```
 
 ### From Source
 
 1) Clone the repository to your local machine and change into the `lula` directory
+
     ```shell
     git clone https://github.com/defenseunicorns/lula.git && cd lula
     ```
 
 2) While in the `lula` directory, compile the tool into an executable binary. This outputs the `lula` binary to the `bin` directory.
+
     ```shell
     make build
     ```
 
 3) On most Linux distributions, install the binary onto your $PATH by moving the downloaded binary to the /usr/local/bin directory:
+
     ```shell
     sudo mv ./bin/lula /usr/local/bin/lula
     ```
