+
 ## Dashboard
 
+After logging in, the user is redirected to the dashboard.
+It shows all the application's features that are available to the respective user group.
+
 ## Change Password
 
+The user can change their password when logged in by navigating to the `Account settings` > `Change password` page.
+They are requested to enter their current password and the new password twice.
+The new password has to fulfill the following requirements:
+- At least 8 characters long
+- At least one uppercase letter
+- At least one lowercase letter
+- At least one number or special character
+
+However, it is not possible to reset the password on their own if the user has forgotten it.
+Instead, it is necessary to contact an administrator, who can reset the password for them.
+
 ## Logout
+
+The user can log out of the application by opening the sidebar through the hamburger icon in the top right corner and clicking on the `Log out` button.
+
+The user is automatically logged out when the session expires, which usually happens after closing the browser.
