+Concept of Alsijil and overview about functionality
+===================================================
+
+Alsijil (Arabic for class register) is a privacy-compliant online class register solution.
+It is not simply the digital equivalent of a paper class book although elements are adopted
+for easier orientation and smoother transition for teachers. For example, there is a weekly
+view of all lessons and a list of all the students in the class. Lesson content,
+notes about the student and also remarks about the learning group can be entered.
+
+However, the application uses the possibilities and therefore the advantages of a digital application.
+The student lists do not have to be filled in by the class teacher,
+but are provided automatically by the system. The timetable is also already stored.
+Documents for general instruction of the students can also be stored centrally for reference.
+The numbers of absences and tardies are automatically summed up
+and missing entries can be displayed at the touch of a button.
+
+In an overview, Alsijil currently provides the following functionality:
+
+- Direct link to the lesson currently taking place
+- Overview with all lessons of one week
+ + Navigation between lessons
+ + Filtering according to learning groups/courses and teachers
+- List of learning groups
+ + List of students with current statistics (absences, lateness, etc.)
+ + printing of the group-specific class register
+- "My overview" for pupils with an overview of "personal notes" such as omissions, lateness, remarks
+- "My overview" for teachers with a list of their own lessons over the last four weeks and the following filtering options:
+ + Specifying the period
+ + Restriction to lessons with or without entry for lesson content
+ + Restriction to certain groups
+ + Restriction to certain lesson contents
+- Only for teachers: Listing of pupils from their own lessons with totalled absences and lateness as well as other remarks
+- Only for teachers with special rights: Listing of all lessons of a specific class in preparation for printing the class register
+- For administrators only: Definition of types of excuses, e.g. for absences due to school-related reasons
+- For administrators only: Determination of types of remark, e.g. HA for homework forgotten
+- Only for administrators: Assignment of special group roles, e.g. for the evaluation of class book entries or access to the print function
+- Only for administrators: Creating group roles

+Basic data concepts
+===================
+
+Relation to Chronos
+-------------------
+
+The class register uses the data from the Chronos app. This means that timetables with
+all current changes such as substitutions, events and exams can be found directly in the class book.
+
+Even basic settings such as lesson times, holidays and public holidays do not have to be
+entered separately in the class book, as they are managed centrally by Chronos.
+
+Concept of lesson documentations
+--------------------------------
+
+Three input fields are provided for the lesson content:
+
+1. **Lesson topic:** The content of the lesson is to be noted here, if necessary with information on the material used.
+2. **Homework:** In this field, the teacher can enter the homework for the next lesson.
+3. **Group note:** Here, there is space for notes that concern the whole learning group, e.g. instructions, dates, or similar.
+
+Concept of personal notes
+-------------------------
+
+Under the tab 'Personal Notes', you will find a student list of the group. The following entries can be made there:
+
+1. **Absent:** This field is not activated by default.
+2. **Lateness in minutes**
+3. **Excused**
+4. **Excuse type:** Several types can be set up for an excuse for absence, e.g. in case a student was absent due to a school event.
+5. **Extra marks:** This item is also configurable. A selection field for missing homework or similar would be possible here.
+6. **Remarks:**
+
+With the appropriate configuration, the student can directly view the data concerning him or her.

+Defining base data
+==================
+
+With sufficient authorisation, two additional menu items appear in the class register menu.
+
+Excuse types
+------------
+
+Additional types of excuse for an absence can be created here.
+This can be useful if you only want to count certain absences.
+For example, if a student is busy at a school event and misses lessons,
+this may not be counted as a normal absence.
+
+Extra marks
+-----------
+
+Some remarks are repeated over and over again, such as 'Forgot homework'.
+In order not to have to write this again and again in the remark field,
+additional marks can be set, which then only have to be clicked on in the class register.
+
+
+Group roles
+-----------
+
+To manage additional rights to the data in the class register, group roles can be defined here.

+System-wide settings for the digital class register
+===================================================
+
+The behavior of the digital class register can be customised
+under `Admin → Configuration → Class Register`. The section contains the
+following preferences:
+
+* **Block adding personal notes for cancelled lessons**: If this option is
+ activated, teachers will not be able to add personal notes for cancelled
+ lessons.
+* **Allow users to view their own personal notes:** With this option, the school management
+ can control whether students should be able to view their own personal notes.
+* **Allow primary group owners to register future absences for students in their groups**:
+ This allows owners of the student's primary group (e. g. the class)
+ to register future absences like doctor's appointments or family celebrations.
+* **Allow original teachers to edit their lessons although they are substituted:**
+ In the case of substitute teaching, absent teachers can be given write-in privileges for the lesson.
+* **Carry over data from first lesson period to the following lesson periods in lessons over multiple periods:**
+ For double (or even more adjacent) lessons, the lesson data from the first lesson period
+ can be automatically carried over to the following lessons.
+* **Carry over personal notes to all following lesson periods on the same day:**
+ For double (or more adjacent) lessons, the personal notes from the first lesson period
+ can be automatically carried over to the following lessons.
+* **Allow teachers to open lesson periods on the same day and not just at the beginning of the period:**
+ Teachers can open lessons earlier on the same day and not just at the beginning of the lesson.
+* **Allow teachers to add data for lessons in holidays:**
+ It is possible to allow entering content for lessons during the holidays.
+* **Allow group owners to assign group roles to the parents of the group's members:**
+ With this being activated, group roles like parent representatives can be managed by the class teacher.

+Overviews about lessons and students
+====================================
+
+Week overview
+-------------
+
+In the weekly overview, all lessons of the week for the respective user are displayed in a weekly schedule.
+Clicking on a lesson takes you to the data for that lesson.
+Above the schedule, you can navigate to the previous or following week.
+It is also possible to filter the schedule according to certain groups or teachers.
+
+My overview (as student)
+------------------------
+
+This menu item provides the student with an overview of the personal notes
+such as tardies, absences and remarks that the teacher has entered in the class register.
+This enables him/her to quickly check whether excuses still need to be submitted.
+
+My overview (as teacher)
+------------------------
+
+This view shows your own hours for the last four weeks.
+A filter can be used to adjust the list with regard to period,
+missing entries, certain groups or certain lesson contents.
+A corresponding symbol in each line immediately shows
+whether entries are still missing for the lesson in question.
+Individual lessons can be called up from the list to add or change entries.
+
+My groups (for teachers)
+---------
+
+With this quick access to your own learning groups,
+you can on the one hand access the relevant student lists
+and the weekly view of the lessons of this group,
+and on the other hand you can print the course-specific class book.
+
+My students
+-----------
+
+With this menu item, the teacher receives a list of all students from his/her lesson.
+From each entry, you can switch to a detailed view to add specific data.
+
+All lessons
+-----------
+
+For the head teacher or the coordinators of certain grades,
+this menu item gives them the possibility to see all lessons of a learning group in a list.
+By means of a filter, the list can be specified to certain entries.
+This makes it possible to call up all lessons with missing entries and
+to send a request for completion of the data to the teachers concerned via a button.

+Viewing and managing lessons
+============================
+
+The lesson documentation can be called up in different ways:
+
+1. **Via 'Current lesson'**: During the current lesson, this is the quickest way to access the lesson documentation.
+2. **Via 'Weekly overview'**: This menu item shows all lessons of the current week. Individual lessons can be clicked on to access the lesson documentation.
+3. **'My Overview'**: This menu item shows teachers a list of all hours worked in the last weeks. Individual lessons can be called up directly.
+
+The lesson documentation consists of four main parts accessible via tabs:
+
+Tab Lesson Documentation
+------------------------
+with lesson topic, homework for the next lesson and notes for the learning group
+
+Tab Personal Notes
+------------------
+with a list of pupils and the possibility to enter tardies, excuses and remarks about the pupil
+
+Tab 'Previous lesson'
+---------------------
+
+(if the lesson content of the lesson in question has been entered) with the date and subject of the previous lesson and a list of the pupils absent from that lesson.
+
+Tab 'More'
+----------
+
+This tab contains several special items not mentioned before:
+
+* **Changes**: Alsijil tracks all changes made to class register entries. This list shows a log of all these changes.
+
+The data can be entered, changed and saved via the relevant forms. In addition, navigation to the previous or next lesson is possible.
