+## Quick Start
+
+### Requirements
+
+**Currently Sail supports both Linux and MacOS. Windows support is planned for a future release.**
+
+Before using Sail, there are several dependencies that must be installed on the host system:
+
+- [Docker](https://docs.docker.com/install/)
+- [Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
+- [Chrome](https://www.google.com/chrome/) or [Chromium](https://www.chromium.org/getting-involved/download-chromium) - not required, but strongly recommended for best [code-server](https://github.com/cdr/code-server) support.
+If chrome is not installed, the default browser will be used.
+
+
+### Install
+
+For simple, secure and fast installation, the following command will install the latest version
+of sail for your OS and architecture into `/usr/local/bin`. You will need to have `/usr/local/bin`
+in your [$PATH](https://superuser.com/questions/284342/what-are-path-and-other-environment-variables-and-how-can-i-set-or-use-them) in order to use it.
+
+```
+curl https://sail.dev/install.sh | bash
+```
+
+### Verify the Installation
+
+To verify Sail is properly installed, run `sail --help` on your system. If everything is installed correctly, you should see Sail's help text.
+
+### Run
+
+You should now be able to run `sail run cdr/sail` from your terminal to start an environment designed for working
+on the Sail repo.
+
+### Browser Extension
+
+To open GitHub or GitLab projects in a Sail environment with a single click, see the [browser extension install instructions](https://sail.dev/docs/browser-extension/).
+
+### Learn More
+
+Additional docs covering concepts and configuration can be found at [https://sail.dev/docs](https://sail.dev/docs/introduction/).
