Update v0.0.6

Marked another roadmap item off with this one. PWA is now officially supported. If you are hosting this through a reverse proxy and you have HTTPS, you should see a button on iOS/Android devices to "install" as an app. If you are accessing it local-only without a reverse proxy, then you will just need to use your respective browser (Safari/Chrome) to "Add to Home Screen" and still take full advantage of the PWA features.

What's Changed

• Add manifest.json for PWA configuration by @NightHawkATL in #17
• Add service worker for asset caching by @NightHawkATL in #18
