+The command line is intended for developers only. Developers can use the command
+line to test and debug Blockstack applications in ways that the Blockstack
+Browser does not yet support. Using the command line, developers can:
+
+* Generate and Broadcast all supported types of Blockstack transactions
+* Load, store, and list data in Gaia hubs
+* Generate owner, payment and application keys from a seed phrase
+* Query Blockstack core nodes
+* Implement a minimum viable authentication flow

+##  How to install the command line

+
+These instructions assume you are using a macOS or Linux system. Installing the
+command line relies on the `npm` dependency manager and optionally Git. If you
+don't find `npm` in your system, <a href="https://www.npmjs.com/get-npm"
+target="\_blank">install it</a>.
+
+To install the command line:
+
+1. <a href="https://github.com/blockstack/cli-blockstack" target="\_blank">Download or `git clone` the command line repository code</a>.  
+
+   Downloading or cloning the repo creates a `cli-blockstack` repository on your system.
+
+2. Change directory into the `cli-blockstack` directory.
+
+   ```
+   cd cli-blockstack
+  ```
+
+
+3. Install the dependencies with `npm`.
+
+   ```
+   npm install
+   ```
+
+4. Build the command line command.
+
+   ```
+   npm run build
+   ```
+
+5. Link the command.
+
+   ```
+   sudo npm link
+   ```
