Building and running your own Tutanota web client

You can build your own Tutanota client and run it locally. Remember that you have to update your Tutanota client on your own. If you prefer the auto-update feature, you can use https://app.tutanota.de directly and upon every update your browser will notify you that the updated app is being installed locally in your browser cache.

Pre-requisites:

Install dependencies: npm install
