+# Golang Chrome Automation using ChromeDP - Example repo
+
+[![Build Status](https://travis-ci.org/ribice/golang-chrome-automation.svg?branch=master)](https://travis-ci.org/ribice/golang-chrome-automation)
+[![Go Report Card](https://goreportcard.com/badge/github.com/ribice/golang-chrome-automation)](https://goreportcard.com/report/github.com/ribice/golang-chrome-automation)
+
+This repo contains a small real world tool built using [chromedp](https://github.com/chromedp/chromedp).
+
+It reads config data from config.json and launches Chrome.
+
+Then it navigates to a Drupal website, logs-in and changes Bootstrap CDN settings.
+
+Detailed explanation is available as a blog-post on my website - [LINK](https://ribice.ba/golang-chrome-automation/).
