-## Hourly builds
-
-This repository is under a Continuous 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.
