 ===== Gain access =====
 To get access to the cluster, speak to your organization's contact with the [[cluster:cluster_management_team|cluster management team (CMT)]]. They will then apply to the [[cluster:cluster_management_team|CMT]] to provision an account for you.
+The first task you **absolutely** need to do when you receive your password is to change it. This is due to you receiving your password via email. If the password is not changed in 1 day, your user access will be revoked, and the process needs to be restarted.
+[[https://forms.gle/dB6uCc4gBngEeUdY6|Here is a form that you can use to apply for access to the cluster.]]
+**It is very important that you change the password as soon as you get access to the cluster.**
+The password can be changed by logging into a machine you have access to using SSH.
+The command to update your password is `passwd`. You will first be prompted for your current password, and then the new password.
 ===== Access the cluster =====
-The machines provided as part of the cluster are on a private network, meaning that in order to access them, you need to be logged on to the [[https://en.wikipedia.org/wiki/Virtual_private_network|VPN]].
+The machines provided as part of the cluster are on a network that is not accessible from the wider internet, meaning that in order to access them, you need to be logged on to the [[https://en.wikipedia.org/wiki/Virtual_private_network|VPN]].
-The VPN is hosted at vpn.ru.is, and to log onto it you need to use your login credentials.
-The VPN is differently accessible depending on the OS you are running:
+Please use a VPN client such as Cisco AnyConnect to log into the RU VPN __vpn.ru.is__. Then use the following log-in credentials:
-==== Windows ====
-The sleep.ru.vpn can be accessed with any vpn client that is compatible with cisco's anyconnect.
+**Username: username@sleep.ru.is**
-An example of this is [[https://openconnect.github.io/openconnect-gui/|Openconnect]]. Alternatively, there is the cisco anyconnect client, which is however proprietary.
-==== Ubuntu ====
+Password: your newly set password
-Similarly to windows, [[https://openconnect.github.io/openconnect-gui/|Openconnect]] can be used to connect to the VPN, both with a command-line-tool and a graphical user interface.
-==== MACos ====
+More detail on the VPN can be found [[cluster:usage_tips:vpn|here]].
+===== JupyterHub =====
+Jupyterhub is a platform that allows multiple users to access computational resources using a graphical user interface. To access the JupyterHub, follow the steps in the [[cluster:usage_tips:jupyter|Jupyter]] article.
+In order to access the JupyterHub, first open a terminal window on your computer and type:
+<code>
+ssh yourusersame@dunwich.sleep.ru.is
+</code>
+Then open a browser and access the page [[https://dunwich.sleep.ru.is/jupyter/
