+### What's Magallanes? ###
+Magallanes is a deployment tool for made with PHP for PHP applications; it's quite simple to use and manage. For more information and documentation please visit http://www.magephp.com/v3
 
-More info coming soon!
+### Installing ###
+Simply add the following dependency to your project’s composer.json file:
+
+```json
+    "require": {
+        "andres-montanez/magallanes": "^3.0"
+    }
+```
+Finally you can use Magallanes from the vendor's bin:
+
+```bash
+$ vendor/bin/mage version
+```
+
+### What happend to version 2? ###
+There is no version 2. I've skipped it and jumpped stright from v1 to v3. This new version of Magallanes is quite radical and different from it's successor. The whole application has been wreritten using Symfony3 Components, so naming it v3 makes a lot of sense.
+
+### Codename... Nostromo? ###
+Each new mayor version of Magallanes will have a codename (like Ubuntu), and in the current version it is Nostromo, like the spaceship from the movie Alien (1979).
