+Greasemonkey script to defrustrate the ThoughtWorks Go user interface experience.
+
+This script adds configuration deeplinks to go pages, to let you jump directly
+to the configuration for whatever build you have open. It also adds color to the
+build output, making it easier to see what's important.
+
+If you have
+[Greasemonkey](https://addons.mozilla.org/en-US/firefox/addon/greasemonkey/)
+in Firefox or
+[Tampermonkey](https://chrome.google.com/webstore/detail/tampermonkey/dhdgffkkebhmkfjojejmpbldmpobfkfo)
+in Chrome, you can
+[install by opening the script](https://github.com/programmiersportgruppe/go-defrustrator/raw/master/go-defrustrator.user.js)
+in your browser.
+
+By default the script will kick in on Go pages served over HTTP on port 8153,
+which is how go listens out of the box.
+If your setup involve go being served over HTTPS or on a different port,
+you'll have to configure the script to be active there.
