 In this case due to how browsers are handling hashes in URLs (the part after the `#`) the only URL the server gets to know is `https://ots.fyi/` which loads the frontend. Afterwards the Javascript executed in the browser fetches the encrypted secret at the given ID and decrypts it with the given password (in this case `mypass`). I will not be able to tell the content of your secret and just see the AES 256bit encrypted content.
 
+## Local development
+
+This repo contains a `Tilefile` to be used with [tilt v0.33+](https://tilt.dev/) to build and start the server for development.
+
+Requirements:
+- Go v1.23+
+- Node v22+
+- Tilt v0.33+
+
+Just run `tilt up` and visit `http://localhost:15641/` for the development server.

 ## Localize to your own language
 
 If you want to help translating the application to your own language please see the [`i18n.yaml`](https://github.com/Luzifer/ots/blob/master/i18n.yaml) file from this repository and translate the English strings inside. Afterwards please [open an issue](https://github.com/Luzifer/ots/issues/new) and attach your translation including the information which language you translated the strings into.
