# Make your Gatsby site a “Progressive web app" (PWA)
“Progressive web app” (PWA) is a term for a new philosophy of building websites.
PWAs help provide native-like features to web apps and require 3 things:
1. A manifest file (provided by gatsby-plugin-manifest)
2. A service worker (provided by gatsby-plugin-offline)
3. The site is served over https
This recipe:
---
Installs the necessary NPM packages.
---
Adds the manifest plugin and the offline plugin to your Gatsby config, which will add a manifest file and a service worker for you.
It also adds a default icon @ src/images/icon.svg (which you can replace afterwards with your own).
---
After running this recipe, your site will be a PWA.
Refer to the documentation for the manifest & offline plugins if there are any
other edits you'd like to make.
