+This is a basic checklist for now, We will update it in the future.
+
+* Fork the repo and create your new branch based on the `development` branch.
+* Commit Unix line endings
+* If you want, try to keep to the theme of black holes/gravity. This can add some fun to your submission.
+* Submit Pull Requests to the development branch only.
+* Before Submitting your Pull Request, merge `development` with your new branch and fix any conflicts. (Make sure you don't break anything in development!)
+* Be patient. We will review all submitted pull requests, but our focus is on stability.. please don't be offended if we reject your PR, or it appears we're doing nothing with it! We'll get around to it..

 1. Install Raspbian 
 2. Run the command below
 
 ### ```curl -L install.pi-hole.net | bash```
 
+#### Alternative Semi-Automated install ####
+```
+wget -O basic-install.sh install.pi-hole.net

 Once installed, [configure your router to have **DHCP clients use the Pi as their DNS server**](http://pi-hole.net/faq/can-i-set-the-pi-hole-to-be-the-dns-server-at-my-router-so-i-dont-have-to-change-settings-for-my-devices/) and then any device that connects to your network will have ads blocked without any further configuration.  Alternatively, you can manually set each device to [use the Raspberry Pi as its DNS server](http://pi-hole.net/faq/how-do-i-use-the-pi-hole-as-my-dns-server/).
