This document provides instructions for a "Groovy Challenge" to save Kermit the Frog. Participants must use Java, Groovy, Gradle and various Groovy/Java APIs to find Kermit's location by decrypting street names from a server, then viewing Kermit at the highest building on the secret street. The document lists the tools and technologies needed, including Java 8, Groovy, Gradle, sdkman.io for installation, HTTPBuilder for HTTP requests, JsonSlurper for JSON parsing, and Grape and Collection APIs. Links are provided for downloading and learning about each item.
