Add a basic website 🌍

[x] Explain project and goal
[x] Add some screenshots
[x] Tech stack, like in repo README
[x] Link to CV/personal site/LinkedIn
[x] Link to Play Store like in repo README
[x] Play Store privacy policy link to this new host
[x] Setup Firebase hosting or Github pages?
- Github pages setup requires a public repository, URL would be http://opatry.github.io/tasks-app.
- Firebase hosting would kinda require to rely on opatry.net subdomain, like https://tasks-app.opatry.net
[x] How would it be published, where sources would land
- sources in app repo undo site/ with nanoc?
- sources in another repo?
- sources in a branch with no common ancestor?

opatry / taskfolio
