+# HyperCLI [![Build Status](https://travis-ci.org/hyperhq/hypercli.svg?branch=master)](https://travis-ci.org/hyperhq/hypercli)
 
-Hyper.sh client for Mac/Linux
+Go version of Hyper.sh client command line tools. 
+
+## Install
+
+### Quick and Easy (Recommended)
+
+Grab the latest version for your system on the [Releases](https://github.com/hyperhq/hypercli/releases) page or build it by yourself as the [instruction](#how-to-build).
+
+You can either run the binary directly or add somewhere in your $PATH.
+
+## Getting Started
+
+#### Before Getting Started
+
+Before you can use Hyper.sh, be sure you've [created a free account with Hyper.sh](http://www.hyper.sh) and [generate your credentials on Hyper.sh](https://docs.hyper.sh/GettingStarted/generate_api_credential.html).
+
+Once the installation and setup completes, enter `hyper config` in your terminal. The CLI will prompt to ask for your API credential:

+
+The credential is stored in a local configuration file `$HOME/.hyper/config.json`. The configuration file is similar to Docker's, with an extra section `clouds`.
+

+
+Or you can use environmental vairables `HYPER_ACCESS` and `HYPER_SECRET` to pass the access key and secret key (CLI will search for these envs before loading the configuration file).
+
+You only need to do that once for your machine. If you've done that, then you can continue.
+
+[See the official docs](http://docs.hyper.sh/) for more detailed info on using Hyper.sh.
+
+#### Actually Getting Started
+
+The easiest way to get started is by digging around.
+
+`$ hyper --help` for example usage and a list of commands
