 Now, *gpu-jupyter* will be accessable on [localhost:port](http://localhost:8888) and shares the network with the other data-source. I.e, all ports of the data-source will be accessable within *gpu-jupyter*, even if they aren't routed it the source's `docker-compose` file.

+## Configuration
+
+The password can be set in `src/jupyter_notebook_config.json`. Therefore, hash your 
+password in the form (password)(salt) using a sha1 hash generator, 
+e.g. the sha1 generator of [passwordsgenerator.net](https://passwordsgenerator.net/sha1-hash-generator/). 
+The input with the default password and salt `asdfe49e73b0eb0e` should yield the hash string as shown in the config file below. **Never give away your own unhashed password!**
+
+Then update the config file as shown below and restart the service.
