-The Electron app implementing my project 'Tanglestash'
+The Electron app implementing my project [Tanglestash](https://github.com/loehnertz/Tanglestash)
+
+
+## Download
+
+You can download the application directly from GitHub.
+It is available for Windows, macOS and Linux.
+Get the latest release v1.0.0 right **[here](https://github.com/loehnertz/tanglesta.sh/releases/tag/v1.0.0)**.
+
+
+## Usage
+
+After starting the application you might first want to setup your node provider.
+This is pre-set to `localhost` which means that you would need to run
+[IRI](https://github.com/iotaledger/iri) (the node software) on your own computer.
+
+A tutorial to setup a node can be found here:
+https://iota.readme.io/v1.2.0/docs/install-iri or http://iota.partners/
+
+At least for retrieving you could also use a node providing service for the public from here: https://iota.dance/nodes
+
+After setting everything up you can either start retrieving a file that
+was persisted in the past using its 'entry-hash' or persist a new file onto the tangle!
+
+Here's an entry-hash to test the application. It's the logo of the app so you need to save it as a `.png` file. It's not encrypted.

+
+
+## Features
+
+- Works on Windows, macOS and Linux
+- Persist any data onto the tangle of IOTA
+- Retrieve data that was persisted with this module beforehand
+- Optionally encrypt your data with a password (via AES)
+- Store a string or even a whole file without any prior conversion
+
+
+## Disclaimer
+
+I know that both the retrieving and persisting to and from the tangle
+are painfully slow compared to a traditional HTTP connection.
+Keep in mind though that this project is more of a proof-of-concept
+rather than a finished product.
