+Sharing state between ``py_func`` calls
+------------------------------------------
+
+Each ``py_func`` item without a ``context_id`` runs in a dedicated subprocess that
+is started and stopped around the call. State cannot be shared between two such
+items using module-level variables.
+
+Two mechanisms are available to share data across calls:
+
+**Using the testium global dictionary**
+
+Inside a ``py_func`` script, the ``tm`` module exposes ``tm.setgd`` and ``tm.gd``
+to read and write the testium global dictionary of the test process. Values stored
+this way are accessible from any subsequent test item (including other ``py_func``
+items) without requiring a shared subprocess.
+
+.. code-block:: python
+    :caption: sharing a serializable value via the global dictionary
+
+    import py_func.tm as tm
+
+    def produce(val):
+        tm.setgd("my_shared_value", val)
+        return val
+
+    def consume():
+        return tm.gd("my_shared_value", None)
+
+Values stored with ``tm.setgd`` must be JSON-serializable (str, int, float, list,
+dict, bool, None). Non-serializable values (objects, connections, file handles…)
+are handled transparently by the local fallback described below.
+
+**Using a shared persistent subprocess (``context_id``)**
+
+When ``context_id`` is set, all ``py_func`` items that share the same identifier
+reuse the same subprocess. The subprocess is kept alive until the end of the test.
+
+This is required for non-JSON-serializable objects (e.g. a socket connection, a
+device handle). Calling ``tm.setgd`` with such a value stores it inside the
+subprocess local dictionary instead of sending it to the main process. It can then
+be retrieved with ``tm.gd`` from any subsequent call that runs in the same subprocess.
