+Understanding the life cycle of orders
+======================================
+
+When integrating pretix with other systems, it is important that you understand how orders and related objects
+such as order positions, fees, payments, refunds, and invoices work together, in order to react to their changes
+properly and map them to processes in your system.
+
+Order states
+------------
+
+Generally, an order can be in six states. For compatibility reasons, the ``status`` field only allows four values
+and the two remaining states are modeled through the ``require_approval`` field and the number of positions within
+an order. The states and their allowed changes are shown in the following graph:
+
+.. image:: /images/order_states.png
+
+
+Object types
+------------
+
+Order
+    One order represents one purchase. It's the main object you interact with and bundles all the other objects
+    together. Orders can change in many ways during their lifetime, but will never be deleted (unless ``testmode``
+    is set to ``true``).
+
+Order position
+    An order position represents one product contained in the order. Orders can usually have multiple positions.
+    There might be a parent-child relation between order positions if one position is an add-on to another position.
+    Order positions can change in many ways during their lifetime, and can also be removed or added to an order.
+
+Order fees
+    A fee represents a charge that is not related to a product. Examples include shipping fees, service fees, and
+    cancellation fees.
+    Order fees can change in many ways during their lifetime, and can also be removed or added to an order.
+
+Order payment
+    An order payment represents one payment attempt with a specific payment method and amount. An order can have
+    multiple payments attached.
+    Order payments have their own state diagram. Apart from their state and their meta information (e.g. used
+    credit card, …) they usually don't change. They may be added at any time, but will never be deleted.
+
+Order refund
+    An order payment represents one refund attempt with a specific payment method and amount. An order can have
+    multiple refunds attached.
+    Order refunds have their own state diagram. Apart from their state and their meta information (e.g. used
+    credit card, …) they usually don't change. They may be added at any time, but will never be deleted.
+
+Invoice
+    An invoice represents a legal document stating the contents of an order. While the backend technically allows
+    to update an invoice in some situations, invoices are generally considered immutable. Once they are issued,
+    they no longer change. If the order changes substantially (e.g. prices change), an invoice is canceled through
+    creation of a new invoice with the opposite amount, plus the issuance of a new invoice.
+
+Here's an example of how they all play together:

+This signal is sent out to collect variables that can be used to display dynamic images in ticket-related PDF layouts.
+Receivers are expected to return a dictionary with globally unique identifiers as keys and more
+dictionaries as values that contain keys like in the following example::
+
+    return {
+        "profile": {
+            "label": _("Profile picture"),
+            "evaluate": lambda orderposition, order, event: ContentFile(b"some-image-data"),
+            "etag": lambda orderposition, order, event: hash(b"some-image-data")
+        }
+    }
+
+The ``evaluate`` member will be called with the order position, order and event as arguments. The event might
+also be a subevent, if applicable. The return value of ``evaluate`` should be an instance of Django's ``File``
+class and point to a valid JPEG or PNG file. If no image is available, ``evaluate`` should return ``None``.
+
+The ``etag`` member will be called with the same arguments as ``evaluate`` but should return a ``str`` value
+uniquely identifying the version of the file. This can be a hash of the file, but can also be something else.
+If no image is available, ``etag`` should return ``None``. In some cases, this can speed up the implementation.
