Please do change this install text to take into consideration that most people will likely be not be logged in as root when they are installing this.

curl -o /usr/local/bin/coast https://raw.githubusercontent.com/coast-framework/coast/next/coast && chmod a+x /usr/local/bin/coast

So you may want to change this to:

sudo curl -o /usr/local/bin/coast https://raw.githubusercontent.com/coast-framework/coast/next/coast && sudo chmod a+x /usr/local/bin/coast

Also, some may prefer not to install into /usr/local/bin directory.
