In order to actually install our extension and see the fruits of our labor so far, we'll need to create a manifest file. This special file, saved in JSON format, controls certain aspects of the extension such as the pages it uses, and the content scripts it can run.
In a new file add the following code:
{
"name": "Web Contacts",
"version": "1.0",
"manifest_version": 2,
"description": "Scrape web pages for Schema.org micro-data",
"browser_action": {
"default_popup": "popup.html"
}
}Save this file in the chrome-extension directory that we created at the start of the task within our main project directory as manifest.json.
