 This repository containts the source code and configuration files of the Arduino Core
 for Atmel's SAMD21 processor (used on the Arduino Zero board).
 
-## Installation on Arduino IDE
-
-This core is available as a package in the Arduino IDE cores manager.
-Just open the "Boards Manager" and install the package called:
-
-"Arduino SAMD Boards (32-bit ARM Cortex-M0+)"
+In particular, this adds support for the Adafruit SAMD Boards such as the Feather M0
 
-## Support
+## Installation on Arduino IDE
 
-There is a dedicated section of the Arduino Forum for general discussion and project assistance:
+Install the Adafruit Board Support package json and then install the Adafruit SAMD board package

-## Hourly builds
-
-This repository is under a Continuos Integration system that every hour checks if there are updates and
-builds a release for testing (the so called "Hourly builds").
-
-The hourly builds are available through Boards Manager. If you want to install them:
-  1. Open the **Preferences** of the Arduino IDE.
-  2. Add this URL `http://downloads.arduino.cc/Hourly/samd/package_samd-hourly-build_index.json` in the **Additional Boards Manager URLs** field, and click OK.
-  3. Open the **Boards Manager** (menu Tools->Board->Board Manager...)
-  4. Install **Arduino SAMD core - Hourly build**
-  5. Select one of the boards under **SAMD Hourly build XX** in Tools->Board menu
-  6. Compile/Upload as usual
-
-If you already installed an hourly build and you want to update it with the latest:
-  1. Open the **Boards Manager** (menu Tools->Board->Board Manager...)
-  2. Remove **Arduino SAMD core - Hourly build**
-  3. Install again **Arduino SAMD core - Hourly build**, the Board Manager will download the latest build replacing the old one.
