+## Introduction
+
+wp-local-env is a cross OS (macOS, Windows, Linux) local development environment for WordPress. It is built on top of [Multipass](https://www.docker.com/) for minimal overhead and the fastest possible boot time.
+
+## Requirements
+
+1. [Multipass](https://multipass.run/) - as this is built on top of Multipass, you will need to first install it for your operating system.
+
+You can find the Multipass installation instructions [here](https://multipass.run/install).
+
+2. [mkcert](https://github.com/FiloSottile/mkcert): mkcert is a simple tool for making locally-trusted development certificates which require no configuration.
+
+You can find the mkcert installation instructions [here](https://github.com/FiloSottile/mkcert#installation)
+

+```
+
+2. Install mkcert with Homebrew
+```
+brew install mkcert
+brew install nss # if you use Firefox

+## Installation
+
+### macOS
+
+Once you have the [requirements](#Requirements) installed, you can install wp-local-env by running the following command:
+
+```
+curl -o- https://raw.githubusercontent.com/jonathanbossenger/wp-local-env/trunk/macos/install.sh > install.sh
+
+chmod +x install.sh
+
+./install
+```
+
+#### Installing the hosts record
+
+Once the installer is complete, run the following command to add the initial hosts record to your system:
+
+```
+sudo sitehosts
+```
+
+This will add a record pointing to the wp-local-env instance and map it to the url `wp-local-env.test`. You can change this url to access the instance in your browser.
+
+If everything worked, you should see the default Debian Apache2 page in your browser.
