Extension Usage Instructions

                        Tamper is a chrome extension that lets you inspect and modify requests made by Google Chrome before they are served to the browser.

IMPORTANT: For Tamper to run you will need to install its companion app using `pip install`, find out more here https://dutzi.github.io/tamper/#install.

---

After installing both the chrome extension and the pyhton package, you will see the Tamper panel in your devtools. Similar to the Network panel, the Tamper panel shows you a list of all requests made by this page. Click on one of these network requests and the response Chrome got will open in your default editor. Make the changes you need and save the file. Once you hit refresh, Tamper will serve Chrome the file you just saved.
