+User management
+^^^^^^^^^^^^^^^
+
+The Education plugin for Orthanc makes the distinction between 3
+categories of users:
+
+* **Administrators** are responsible for the configuration of Orthanc
+  and for the management of the collections of medical images
+  (referred to as "projects"). It is up to the administrators to
+  upload the DICOM images, to create the projects, to dispatch the
+  images among the different projects, and to associate projects with
+  instructors and learners.  To this end, administrators have access
+  to the administrative interface of the Education plugin, as well as
+  to :ref:`Orthanc Explorer <orthanc-explorer>` and :ref:`Orthanc
+  Explorer 2 <orthanc-explorer-2>`.
 
-This plugin adds a dedicated button to Orthanc Explorer, which
-provides an easy, fast access to the OHIF viewers ():
+* **Standard users** represent either instructors (teachers) or
+  learners (students). These users cannot modify the configuration of
+  the platform, upload medical images, or distribute images across
+  projects. Instructors can modify project-specific settings based on
+  their pedagogical objectives, such as controlling project visibility
+  or selecting which viewers are available for a given project. A user
+  may act as an instructor in certain projects and as a learner in
+  others. For this reason, the "teacher vs. learner" terminology is
+  avoided, as it implies a fixed role for each user.
+
+* **Guest users** are users who are not authenticated by the
+  platform. They behave like learners but can only access projects
+  with public visibility. This functionality can be used to publish
+  massive open online courses (MOOCs) through the standalone mode of
+  operation.
+
+The way the Education plugin authenticates administrators and standard
+users is specified in the :ref:`configuration file of Orthanc
+<configuration>`. The following authentication mechanisms are
+available:
+
+* **Login**. In this case, the Education plugin displays a login page
+  where the user can enter their credentials, which are specified in
+  the configuration file.
