+# hostctl
+
+> Manage your /etc/hosts like a pro!
+
+This tool gives you more control over the use of your `hosts` file. You can have multiple profiles and enable/disable as you need.
+
+
+## Why?
+
+It is a tedious task to handle the `hosts` file by editing manually. With this tool you can automate some aspects to do it cleaner and quick. 
+
+
+## Installation
+
+Go to [release page](https://github.com/guumaster/hostctl/releases) and download the binary you need.
+
+
+## Features
+
+  * Manage groups of host names by profile.
+  * Enable/disable complete profiles.
+  * add/remove groups of host names.
+  * add profiles directly from a `.etchosts` file that you can add to your vcs.
+
+
+## Usage
+
+`hostctl list`
