## Description

Diffy helps to verify plugin updates by taking screenshots of your site before and
after update and comparing them.

Ideally you expect zero changes after running updates.

### Set up instructions

You need to have active Diffy (https://diffy.website) account in order to use this
plugin. Plugin will also allow you to create an account and project for your site
with one click.

Diffy provides 2 weeks trial to cover up to 100 pages of your site.

Your site should be publicly available. Diffy runs workers from AWS infrastructure
by using single IP address 3.216.56.216. Whitelist it if needed.

Once you registered an account, please create a project. You need to specify your
site’s URL as Production environment. Add your site’s URLs to the project. Diffy
can parse sitemaps if you like. Meanwhile you will want to have just key pages covered
by visual regression testing and not every page of your site.

After setting up the project, generate API key under My Account -> Keys.

Enter project id and API Key to Diffy’s plugin settings page and you should be good
to go.

### How it works?

During plugins update process plugin will call Diffy via API to create set of screenshots
before the update. Expect that it will make update process longer.

After screenshots are ready update process will continue. Once updates are completed
plugin will call Diffy once again to create second set of screenshots and compare
them with your “before” version.

You will receive an email notifications about screenshots and diffs being completed.

Review the report and ensure that nothing got broken.
